Volume & Tier Pricing Calculator
Build an internal tool that auto-applies the correct volume-break and customer-tier pricing to quote lines, shows which rule fired, and holds the result for a reviewer to approve before it locks onto the quote.
Inside sales enters a customer and quantities, the tool auto-applies the correct tier and volume break (honoring effective dates and showing which rule fired), a reviewer approves, and you get clean, consistently priced quote lines.
Before you start
- A free Supabase account
- A free Vercel account
- A free Resend account
- Your tier/volume price-rule list and customer tier assignments (a Google Sheet or CSV is fine)
The problem this kills
Tiered pricing looks simple on paper and falls apart in practice. One rep gives the gold-tier customer the 500-unit break; another forgets the customer moved up a tier last quarter; a third applies a price list that expired in March. The rules live in a spreadsheet nobody fully trusts, overlapping breaks collide, and "which price is correct?" turns into a Slack thread every single quote.
The result is margin leakage you can't even measure - some customers underpaid, some overpaid and churned, and your finance team can't reconcile any of it. The pricing logic exists; it's just trapped in people's heads and applied by hand, differently every time.
What you'll build
A small, private web app for your inside sales and pricing team. A rep picks a customer, enters the quantities, and the tool does the thing humans keep getting wrong: it finds the customer's tier, applies the correct volume break for each line, honors effective dates so expired rules never fire, resolves overlapping rules with a clear winner, and shows exactly which rule produced which price. Nothing locks onto the quote until a reviewer approves the applied pricing. Then you get clean, consistent, defensible quote lines - and a record of how every price was reached.
What's inside the Implementation Plan
- It starts by interviewing you about your business. Before it builds anything, the plan has the AI agent ask you about your real pricing rules, your tier names, how volume breaks work, your effective-date conventions, and your messiest edge cases - then it tailors the data model and the pricing math to your business instead of a generic template. You confirm a short spec before a single line is written.
- A step-by-step build you paste into Claude Code, one prompt at a time.
- A pricing engine that resolves overlapping rules, honors effective dates, and records the winning rule for every line.
- A reviewer approval gate so applied pricing is checked by a person before it's final.
- Duplicate protection keyed on quote ID + line so the same quote line can't be priced twice.
- A "No API yet?" fallback that loads your rules and tiers straight from a Google Sheet or CSV and exports clean, system-ready priced lines - so you can ship it today with zero integration work.
The governance it includes (this is the point)
- Login so only your team can open the tool.
- Row-level security so each organization only ever sees its own customers, rules, and quotes.
- A full audit trail - who applied which pricing, who approved it, and exactly when.
- A human-in-the-loop approval gate - the tool drafts the priced lines, a reviewer approves, and only then is the pricing locked onto the quote.
- Duplicate guards keyed on quote ID + line so the same input can't be processed twice.
Who it's for
Inside sales reps and pricing analysts who quote against tiered or volume-break price lists and are tired of doing the lookup by hand - and the sales-ops or finance lead who needs every applied price to be consistent, dated, and auditable.
