Calculators and planning tools for small business operations.
Instant, mobile-friendly planning aids. No login, no signup, no wait. Each tool includes the formula or methodology so you can verify the result.
GST Calculator
Estimate CGST, SGST, IGST, and total invoice value from a taxable amount. Mobile-friendly, no login required.
Billing Software Cost Calculator
Estimate annual billing software cost from team size, counters, printers, and support level. Planning ranges only.
Retail Day-End Reconciliation Calculator
Compare expected cash with counted cash and spot variance before close. Use as the day-end starting point.
QR Scanning Capacity Calculator
Estimate theoretical gate throughput from scanner count and observed speed. For event planning, not performance promises.
POS Employee Permission Matrix
See which counter actions each role — cashier, manager, owner — should be able to perform. Visual, printable.
Reverse GST Calculator
Work backwards from a total that already includes GST to the taxable value and the tax itself, with the CGST, SGST, or IGST split.
Profit Margin Calculator
Gross profit, gross margin, net profit, and net margin from revenue and costs. Handles revenue that includes GST.
Receivables Aging Calculator
Bucket open invoices into 0-15, 16-30, 31-60, 61-90, and 90+ day bands to see what is actually overdue, and by how much.
Markup vs Margin Calculator
See the difference between a markup on cost and a margin on price, and convert between the two.
Project Profitability Calculator
Compare quoted value plus approved change orders against direct cost and internal hours, and flag margin below your own threshold.
Lead Response Time Calculator
What slow first replies may be costing you in rupees each month, as a range rather than a false-precision figure. You supply the cool-off time; we do not assume one.
Inventory Reorder Calculator
Reorder point, safety stock, and reorder quantity from demand, supplier lead time, and a service-level target.
Lead Follow-Up Planner
Build a follow-up schedule for open leads with the next action and date for each one.
Quote Estimator Calculator
Price a job from hours, internal cost, materials, target margin, and a GST slab — and see what that margin actually costs you in unpaid hours.
Agency Utilisation Calculator
Available hours against hours already booked, at your own billable target. A capacity model, not a productivity score.
CRM Migration CSV Builder
Paste your existing customer rows and see what is wrong with them before you import: missing fields, duplicate phones and emails, bad dates, inconsistent statuses.
Invoice GST Breakdown Calculator
Split an amount into base, CGST, SGST or IGST and total, reading either a tax-inclusive invoice or a tax-exclusive base, and see the tax as a real share of the invoice.
Safety Stock Calculator
Safety stock and reorder point from average daily demand, demand variability, lead time and a named service level — with the normal-distribution assumption stated rather than hidden.
Sales Pipeline Planner
Open deals per stage with a value and a close probability, giving total open value, weighted pipeline, and the gap between value-weighted and count-weighted probability.
Scope Change Cost Calculator
What a scope change costs before you quote it: extra hours or cost, a contingency, the new total, the delta, and the price that holds your original margin.
Retainer Profitability Calculator
The effective hourly rate a retainer actually funds once the hours are counted, plus allowance consumed, cost, gross profit and margin. The number retainer discussions usually skip.
Quotation Generator
Build line items with per-line tax and optional cost, then get subtotal, total, margin and markup, and copy the summary. A working calculation to paste, not a signed quote.
Payment Follow-Up Planner
List outstanding invoices for days outstanding, 0-30 / 31-60 / 61-90 / 90+ ageing, and a worklist ranked by value and age, with recorded payment promises checked against today.
