Pricing & Rating
Priced and rated by rules
Define your charges once as rules—conditions and formulas. At bill time, the same rules rate every subscription's usage into exact charges. Any pricing model, no code.
Any pricing model
Flat, tiered, volume, usage-based, or context-sensitive — priced by rules, not rigid templates.
No-code charging logic
Build rules from conditions and formulas, chain components, and reuse them across plans.
The same rules price and rate
The rules that define a plan's price are the rules that rate each subscription's usage at bill time.
Test before you bill
Dry-run any plan with sample inputs and see every line calculated before it goes live.
Customer Account Model
One account, one invoice
A customer can have many billing accounts. Each account rolls its base subscriptions—and their optional add-ons—into a single invoice, consolidated on the summary where account-level charges and taxes are calculated.
Billing account = one invoice
All subscriptions under a billing account bill together on a single invoice.
Base plus optional add-ons
Each base subscription can carry add-on subscriptions, every one priced on its own rules.
Consolidated on the summary
Multiple subscriptions roll up into one summary—where account-level taxes and totals are calculated.
B2C and B2B, one model
A single residential account or a multi-site enterprise group use the very same structure.
The Billing Engine
Run the full cycle
Most tools stop at generating an invoice. Billspree runs the whole cycle—draft, review, adjust, post, and publish—across every account in one batch, so every bill reflects the customer's true position before it goes out.
Batch every account at once
One bill run processes every account due for the period—hundreds or thousands of invoices together.
Draft, review, then post
Nothing is final until you post. Review and adjust drafts before anything reaches a customer.
Arrears and credits applied
Unpaid balances carry forward and available credits apply—so every draft shows the true net position.
Usage and estimation built in
Ingest meter reads and usage, and estimate missing reads so a bill run never stalls.
Customer Portal
Your customers see everything
A branded self-service portal where customers view every itemized bill, track their full usage trend over time, pay online, and manage their own subscriptions—no call to your team.
Itemized bills, no black-box totals
Every fee, tax, and surcharge shows as its own named line—not a single lump sum.
Full usage trend over time
Customers see their consumption trend across periods, not just this month's amount.
Pay online, self-serve
Saved payment methods, full payment history, and one-click pay in one place.
Manage their own subscriptions
Sign up, accept quotes, and change plans without a call to your team.
AR Management
Every balance, provable
Behind every invoice is a formal AR subledger. Credit notes, payments, and adjustments all post as real entries—so a customer's balance is the sum of every transaction on record, never a number someone edited.
A subledger per account
Every billing account has its own running ledger with full transaction history.
Credit & debit notes that post
Adjustments post as real entries against the bill—not silent edits to a total.
Aging and dunning
Aged receivables, late-payment surcharges, and scheduled reminders to lower DSO.
Cash application
Match payments to open invoices by hand or from a bank-statement upload.
Reporting
Reports finance can act on
Pull the reports your finance team actually runs—aged receivables, customer ledgers, collections, and sales by customer—and export them for month-end close and reconciliation.
Aged receivables
See exactly who owes what, bucketed by how long it's been overdue.
Customer ledger
Every invoice, payment, and credit for any customer, end to end.
Collections & cash
All payments received in a period, ready for bank reconciliation.
Export anywhere
PDF for review, CSV or Excel for deeper analysis.
Integrations

REST API, developer-first
Drive customers, subscriptions, meters, and bills with your own API keys.
Webhooks on every event
React to created, updated, cancelled, and payment-failed—automatically.
Provision automatically
Turn a service on or off in your platform the moment a subscription changes.
Multi-tenant ready
Pass tenant or org IDs through every call so the right account updates.
