Construction contractor software with no TDS or TCS, no e-way bill, no retention or running-account bill, and no BOQ or measurement book — a quotation-to-collection record chain, not a site accounting system
A contractor does not bill on the first of the month. A contractor bills on work that was done, measured and certified, and then waits for money that may be reduced, withheld or released on a schedule of somebody else’s choosing. NoxOrigin holds the quotation, the variation, the invoice and the collection as one connected record on the project. What is not here is TDS or TCS recording, e-way bills, a retention or running-account model, a BOQ or measurement book, subcontractor compliance tracking, or any capture of a quantity from a site photograph. A scope change is a new quote on the same project, never an edit to an old one.
Five things this name usually means, and the one record chain you get instead
Deduction handling, e-way bills, retention and running accounts, BOQ-based estimating, and measurement certification. None of the first four exist in NoxOrigin in any form, and the fifth happens outside it. The record chain is what is here in their place, and it is genuinely useful for a contractor billing on progress — provided you are not waiting for a construction accounting system to appear after the trial.
TDS and TCS
There is no TDS field, no TCS field, no deduction report and no deduction certificate. A deduction your contract requires is a figure your accountant holds and the bank applies; NoxOrigin is not the place it lives, and the invoice in the system will read higher than the money that arrived. This is not a roadmap gap. A deduction ledger is a statutory product with its own formats, and NoxOrigin does not file GST returns or any other statutory return.
The e-way bill
There is no e-way bill generation, no e-invoice generation, no IRN, no QR code on the invoice for that purpose, no consignment note, no transporter detail and no vehicle number. If your process requires an e-way bill to move material off site, that document comes from a separate product or from your logistics provider, and no plan on this site changes that.
Retention and the running account
There is no retention field, no retention ledger, no R.A. bill, no running-account statement and no release schedule. The moment a project withholds money against certified work, the billing model you actually run stops being the one in this system. That is the single largest reason a contractor reading this page should stop and buy a construction accounting product instead.
The BOQ and the measurement book
There is no BOQ record, no item rate, no measurement-book entry, no certified quantity and no valuation certificate. A quote here is a set of lines with quantities and rates. Who measured the work, on what date, against which drawing revision and to what standard is held outside NoxOrigin, which means the system can show you what you billed and not why that number was correct.
What there is instead: quotation, variation, invoice, collection, on one project
A quote with lines and tax treatment. A variation as a new quote on the same project. An invoice raised against the project. A payment recorded and allocated against that invoice. Four records, connected, so that quoted value, billed value, collected value and outstanding value are four readable states of the same project instead of four figures reconstructed from memory at year end.
A project routine where the variation is written down before the work is done
Six steps. Step three is the one that separates this from a spreadsheet: a scope change is a second quote on the same project, so the value you first billed against is still readable and the variation value is findable rather than buried in a revised total.
Hold the client and the project once, before any money moves
A project record is the only place a quote, a variation, an invoice and a payment can meet. If the client exists twice, the project exists under two names, and the variation sits in a site diary, the chain breaks at the first claim and nobody notices until the reconciliation. Naming the client and opening the project once is the cheapest control on this page.
Quote the scope as lines with a tax treatment, not as a BOQ
Each line carries a description, a quantity, a rate and a tax treatment, and the totals are arithmetic you can check by hand. What the quote cannot do is break the work into measured items with an approved rate for each, because there is no BOQ record here. Where your work genuinely is measured item-by-item, that structure belongs in the certification process and the quote describes the commercial consequence of it.
Raise the variation as a new quote on the same project, before it is performed
This is the step the rest of the page is arguing for. A scope change is a new quote with its own total on the same project. The original quote is not edited, so the value you first billed against stays intact, and the variation value is findable rather than absorbed into a revised total nobody can reconstruct. A variation performed first and quoted afterwards is a variation you have already agreed to work for.
Invoice the certified work, and keep the certification outside the system
The invoice says what you are asking for and on what basis: the quote or the variation it derives from, the lines, the tax treatment, the total. It does not certify the work, because NoxOrigin has no measurement book and no certification record. That is a real limitation, and it is better to have it named here than discovered at the second claim when nobody can show what the first one was measured against.
Record the money as a payment, and allocate it to the invoice
An invoice and a payment are different records. Money received does not reduce anything until a person allocates it. Paid is a projection of allocations rather than a stored flag, which is why a large received-but-unallocated amount is worth chasing on the day it lands, and why an outstanding figure from an unmanaged allocation queue cannot be trusted. If the client withheld something, the invoice still reads full and the difference has to be resolved deliberately.
Read quoted against billed against collected, and act on the gap
Quoted is the sum of the quote and every variation. Billed is the invoices. Collected is the allocations. Outstanding is the difference. Read together on one project, they tell you which variations are still unbilled and which invoices are still unpaid. The retained amount and the deducted amount do not appear in that arithmetic at all, because this system does not hold them.
One project, one claim, one variation, and the two numbers this system cannot show you
Every figure in this section is constructed for this page so the arithmetic can be checked by hand. It is not a NoxOrigin result, not a contractor’s record, and not a benchmark. The 18% GST appears only so each addition can be verified; it is not a tax position, and NoxOrigin does not file GST returns or any other statutory return. Nothing here is a claim cycle time, a percentage of billing collected, a retention dispute rate or a claim rejection rate, and this page publishes none of those.
The quote that opened the project
A scope quoted at 400,000 in lines with a tax treatment. GST at 18% is 400,000 × 0.18 = 72,000, so the quote total is 400,000 + 72,000 = 472,000. That is a commercial figure: a set of lines with quantities and rates. It is not a BOQ, and nothing in it records an approved item rate for a measured item.
The first progress claim on certified work
Work the client’s engineer measured and certified comes to 160,000. GST at 18% is 160,000 × 0.18 = 28,800, so the invoice total is 160,000 + 28,800 = 188,800. NoxOrigin can record that you invoiced 188,800. It cannot record who measured the work, on what date, against which drawing revision, or to what standard — there is no measurement book here, and that certification stays in the site file.
The retention the client withholds, and the number to hold in your head
At a constructed 2.5% on the certified value, 160,000 × 0.025 = 4,000 is withheld. NoxOrigin has no retention field, no retention ledger and no release schedule, so that 4,000 is not held anywhere in the system as money you own. When it is released, someone raises an invoice for it as an ordinary line: 4,000 + 720 tax at 18% of 4,000 = 4,720. Until that invoice exists and is paid, this system has no record of the release at all.
The variation, which is a second quote and not a revised total
The client asks for extra work priced at 45,000. GST at 18% is 45,000 × 0.18 = 8,100, so the variation quote totals 45,000 + 8,100 = 53,100. The project’s quoted value becomes 472,000 + 53,100 = 525,100, and the original 472,000 quote is still on the project unchanged and still readable. Had the first quote been edited to absorb the variation, the 188,800 you billed against would have had no surviving document behind it.
The two deductions this system does not hold
At a constructed 1%, TDS on the certified value is 160,000 × 0.01 = 1,600, and TCS on a payment of 120,000 is 120,000 × 0.01 = 1,200. NoxOrigin has no TDS field, no TCS field, no deduction report and no e-way bill, so those two figures live in your accountant’s books and in the bank’s advice and appear in no record on this page. Whether any deduction applies, at what rate, and how it is treated is your chartered accountant’s call, not a feature of this page.
The money, and why one payment is two actions
The client transfers 188,800 as two amounts, 120,000 and 68,800, which is 120,000 + 68,800 = 188,800. An invoice and a payment are different records, and paid is a projection of allocations rather than a stored flag. Until both amounts are allocated to the invoice, that invoice does not read as paid, and a received-but-unallocated balance has reduced nothing. On a project where money arrives in slices against several claims, the allocation step is the entire discipline.
What the project page can actually read back
Quoted 525,100 across two quotes. Billed 188,800. Collected 188,800. Outstanding nil on that invoice, with a further 4,000 of retention not yet invoiced. That is the honest total, and it is worth noticing what is absent from it: the 1,600 of TDS, the 1,200 of TCS and the 4,000 of retention are all real money that this arithmetic does not describe, because this system does not hold them.
The figure this page will not give you
There is no average claim cycle time, no percentage of certified billing collected within a period, no retention dispute rate, no claim rejection rate, no average variation ratio and no benchmark for any of them. Each would be a ratio against a denominator chosen after the result is known, and a denominator chosen after the fact is an argument rather than a measurement. Two quite different contractors can show the same collection rate on entirely different contract terms, which is exactly why we will not print one here and let you assume yours would resemble it.
What a contractor asks for, and the honest answer
If the first five rows apply to you, stop here and buy a construction accounting system with a measurement book. The rest is what NoxOrigin does with a quote, a variation, an invoice and a collection somebody has recorded.
| What a buyer asks for | In NoxOrigin |
|---|---|
| Record TDS and TCS deductions | No. No TDS field, no TCS field, no deduction report and no deduction certificate. A required deduction lives in your accountant’s books and in the bank’s advice, not here. |
| Generate e-way bills and e-invoices | No. No e-way bill, no e-invoice, no IRN, no transporter or vehicle detail. NoxOrigin also does not file GST returns, handle reverse charge or determine place of supply. |
| Hold retention and raise running-account bills | No. No retention field, no retention ledger, no R.A. bill, no release schedule. Released retention has to be invoiced as an ordinary line to exist at all. |
| Keep a BOQ and a measurement book | No. No BOQ, no item rate, no certified quantity and no measurement entry. A quote is a set of lines with quantities and rates. |
| Track subcontractor compliance | No. No subcontractor onboarding, no work registration, no permit or licence expiry, no insurance-document tracking and no approved-vendor workflow. |
| Derive a quantity from a site photograph | No. There is no photo-to-quantity capture, no image measurement and no automated takeoff. A photograph documents a condition; it is not a certified measurement. |
| Hold a quotation, a variation, an invoice and a payment on one project | Yes. Quotation, variation as a new quote on the same project, invoice, and a payment recorded and allocated against it, on the same project record. |
| Keep the original quote readable after a scope change | Yes. A scope change is a new quote with its own lines and total. The original quote is never overwritten, and there is no change-request record, milestone or deliverable record, contract editor or e-signature. |
| Read quoted value against billed value | Yes. Quoted is the sum of the quote and every variation raised on the project; billed is the invoices; collected is the allocations; outstanding is the difference. |
| Post the claim to the statutory books | No. NoxOrigin does not file GST returns or any other statutory return, does not determine how a deduction or a retention release should be treated, and holds no bank connection or credential. |
Where this is the wrong tool
Construction billing software is judged by what it refuses to imply. The list below is the set of things a reader is most likely to assume are present because the page title sounds like they are.
If retention and running-account bills are the core of how you get paid, this is the wrong product
No retention field, no R.A. bill, no running-account statement and no release schedule. A billing cycle that is not monthly depends on certified work and on money released against it, and neither of those exists in NoxOrigin. Buy a construction accounting system and let this page cost you thirty seconds.
If TDS, TCS and e-way bills have to be in the same system, this is the wrong product
No deduction fields, no e-way bill, no e-invoice, no reverse-charge handling, no place-of-supply determination and no statutory return filing. Those belong to a dedicated compliance product and to your chartered accountant.
If the measurement book is the source of truth, this is the wrong product
No BOQ, no item rate, no certified quantity, no measurement entry and no valuation certificate. NoxOrigin records the commercial consequence of a certification it does not perform and cannot see.
No timesheet, no labour attendance, no payroll
A labour contractor is a party on an invoice, not a workforce record. There is no muster roll, no wage register, no leave or overtime record and no payroll. If site labour is a compliance problem you are managing, that is a statutory product, not a billing one.
Subcontractor compliance is not tracked here
No subcontractor onboarding, no work registration, no permit or licence expiry tracking, no insurance-document expiry, and no approved-vendor workflow. An approved subcontractor list with expiring papers is a compliance product.
A site photograph does not become a quantity
There is no photo-to-quantity capture, no image measurement and no automated takeoff. A photograph documents a condition. It is not a certified measurement, and inferring one from it produces a number that looks like evidence and is not.
An invoice and a payment are different records, and paid is a projection
Money received reduces nothing until a person allocates it, and paid is derived from allocations rather than stored as a flag. On a project where money arrives in slices against several claims, the allocation step is the whole discipline, and skipping it leaves the outstanding figure unreadable.
Run project billing on the plan that matches your active project count
Growth is ₹1,600/month or ₹15,000/year, includes a 30-day trial, 10 users, 50 active projects, and 10,000 contacts. Say this plainly rather than let it be assumed: these are NoxOrigin platform plans. NoxCRM, Nox-Billings and Nox-Tickets are scoped custom deployments, quoted and priced separately against your own configuration, and the platform plan price never applies to any of them. A retention model, a measurement book and deduction reporting are not plan questions, so if those are what you need, say so in the conversation — that is a different product conversation, not a pricing one.
Construction contractor questions, answered before you buy
Does NoxOrigin record TDS or TCS?
No. There is no TDS field, no TCS field, no deduction report, no section-wise deduction summary and no deduction certificate. If your contract or your accountant requires a deduction, NoxOrigin cannot hold it, cannot net it against an invoice and cannot report on it. A deduction held outside the system means the invoice in NoxOrigin and the money actually received are two different figures, and the difference is yours to reconcile by hand. NoxOrigin also does not file GST returns, does not generate e-invoices, does not issue e-way bills, does not handle reverse charge, does not determine place of supply, and holds no bank connection or bank credential of any kind.
Is there a retention model or a running-account bill?
No. There is no retention field, no retention ledger, no R.A. bill template, no release schedule and no running-account statement. Withheld money is not held anywhere in NoxOrigin as an amount you own. When retention is released, somebody raises an invoice for it as an ordinary line, and until that invoice exists and is paid, the system has no record of the release at all. A construction billing product whose central model is retention against certified work is a different product, and this page is not it.
Can it hold a BOQ or a measurement book?
No. There is no BOQ record, no measurement-book entry, no item rate and no quantity-versus-ordered structure. A quote here is a list of lines with quantities and rates, not a bill of quantities. The certification of work — who measured it, on what date, to what standard — happens outside NoxOrigin and is not recorded here. The consequence is worth stating plainly: NoxOrigin can record that you invoiced ₹160,000 of work, and it cannot record why that figure was the right one.
How does a scope change actually work?
It is a new quote on the same project, with its own lines, its own total and its own number. The original quote is never overwritten, so the figure you billed against is still readable a year later. There is no change-request record, no milestone record, no deliverable record, no contract editor and no e-signature anywhere in NoxOrigin. The practical consequence is that variation value is only visible because someone raised a new quote, and a variation discussed verbally at the site gate is worth nothing to you until somebody writes it down.
Does it track labour, attendance or payroll?
No. There is no timesheet, no daily labour attendance, no muster roll, no wage register, no overtime or leave record, and no payroll of any kind. A labour contractor is a party on an invoice, not a managed workforce inside the system. Payroll is a different product with statutory obligations attached to it, and /time-and-billing-software is the same boundary stated from the billable-time side.
Does it do subcontractor compliance, or turn site photos into quantities?
No to both. There is no subcontractor onboarding record, no work-registration or permit tracking, no labour-licence or GST-registration expiry tracking, no insurance-document tracking, and no approved-vendor compliance workflow. And there is no site-photo-to-quantity capture, no photo measurement, no image-to-boolean takeoff. A photograph is not a measured quantity, and a system that infers one from the other is manufacturing a number nobody certified.
Can it chase retention or recover a rejected claim for me?
No. There is no dunning, no automatic reminder escalation, no card-on-file, no auto-debit, no credit bureau and no recovery engine. What exists is an outstanding figure with a promised date on it, so the queue is decided by a written rule rather than by whoever shouts loudest. /debt-collection-and-recovery-software covers that boundary on its own terms, and a rejected progress claim is a measurement and certification dispute before it is a collection problem.
Is this included in the platform plan price?
The plan prices on this page are NoxOrigin platform plans. NoxCRM, Nox-Billings and Nox-Tickets are scoped custom deployments, quoted and priced separately against your own configuration, and the platform plan price never applies to any of them. If what you need is a running-account model, a measurement book or deduction reporting, say so in the conversation rather than assuming a plan price covers it, because no plan on this site adds those.
Tell us whether you need a measurement book.
If you do, we will say so before you spend any more of your time here, because NoxOrigin has no BOQ, no measurement book, no retention or running-account bill, no TDS or TCS recording, no e-way bill and no subcontractor compliance tracking, and no plan on this site changes that. What it does have is the record a progress bill needs: a quote, a variation written as a new quote on the same project, an invoice, and a payment somebody allocated — so that the value you first billed against is still readable a year later.
