Add each product you sell and the plans customers can choose: a fixed fee, a price per seat and a price per unit of usage beyond an included amount, billed monthly or yearly. Your website asks the public pricing endpoint for the buyer's country and gets every price back with the right VAT.

Brands and company
Your legal entity issues every invoice. Each brand you sell keeps its own products, plans, customers and partners, its own logo and colour, and its own website at yourbrand.qaptu.app or on the brand's own domain.
Brands
Connected platforms
Your website reads your plans and prices from the public pricing API. Your software calls the Qaptu API with an API key: it names customers and services with your own ids, reports usage and asks what a service may do. Cache the answer: if Qaptu is unreachable, keep working with the last one.

}Ways of working
Keep the whole experience inside your product, use the customer portal we run under your brand, or combine both. The same contracts, billing and service state sit underneath.
Integrated into your product
Your customer never needs to enter a Qaptu portal. They sign up, choose a plan, check invoices and manage their account in your software. Your backend talks to Qaptu through APIs and signed webhooks.
Qaptu stays behind the scenes as the billing and subscription engine.
White-label customer portal
Your customer uses the website and portal we run with your name, logo, colour and domain. They can sign up, accept terms, manage plans and payment methods, and download invoices there.
We operate the customer-facing area; it looks and feels like part of your company.
Hybrid
You do not have to choose one model for everything. Keep the moments that define your product and hand the administrative ones to the portal.
Provisioning
Some software is ready the moment someone subscribes. Some needs your team to install, configure or check each customer first. You choose how Qaptu hands a new subscription to you.
When a customer subscribes, changes plan, cancels or stops paying, Qaptu notifies your software through signed, retried webhooks and the Qaptu API. Services are set up, changed or restricted with no one in the middle.
Every new subscription waits until your team confirms it. Only then is it billed and your software notified. Made for software you install, configure or check for each customer.
Billing
A monthly billing run prepares one invoice per customer, issued by your company in the series of the brand it belongs to, plus a wholesale invoice for each reseller. Run it again and the drafts are refreshed; issued invoices are never touched.
Drafts per customer with fixed, per-seat and usage lines, ready to review and issue.
Each brand has its own series, such as AB2026-000001, numbered when an invoice is issued and never before.
Correct an invoice in part or in full, in the brand's own credit-note series. On a paid invoice, the credit note tracks the refund you make.
Charge each plan in advance or at the end of the period. Usage is always billed after it happens.
Customers who start or cancel mid-month pay only for the days they had.
Collections
The money never passes through Qaptu. It prepares the collection, records the result and updates the invoice; your bank and your payment provider move the money straight to you.

Collection date October 5, 2026 · file for your bank
Unpaid invoices
When an invoice is overdue, the service moves through grace, restricted and suspended on your schedule, and your software reads the state. How you follow up with your customer is your decision.
Choose after how many days an overdue service goes into grace, is restricted or is suspended.
Recording a payment or voiding an invoice re-evaluates the service at once.
See who is overdue, since when and in which state, with every change on record. How you follow up is up to you.
Pin a service to a state by hand when you have agreed something with the customer.

Example schedule. You set the days, and you can pin a state by hand at any time.
Contracts
Each brand publishes its own terms for customers and for partners. When you change them, you publish a new version; what each person accepted stays on record.
Customer terms and partner terms per brand, each with its versions.
Customers accept when they subscribe; partners accept when they take up your invitation.
Who accepted, when, from where, and a fingerprint of the exact text they saw.
You stay in control
Qaptu is not a marketplace and not a merchant of record. It gives you the tools to sell and get paid, and then gets out of the way: no one sits between you and your customers, and there is no revenue share.
You sell to your customers under your own name and your own brands, on your own websites. Every invoice is issued by your company.
Direct debit through your bank, cards through your own Stripe or Redsys account. The money goes straight to you: nothing is held, delayed or taken as a cut.
You decide how to follow up on a late invoice. Qaptu gives you the service states, the history and the list of who is overdue.
Shadow runs
Already billing with another system? Run Qaptu in shadow mode next to it. Shadow drafts are calculated like real ones but are never issued, so you can check every line against what you invoice today and switch when the numbers match.
Recreate your plans and connect your customers with your own ids.
Get drafts for the month that are never numbered or sent.
Compare line by line with your current invoices, then start issuing them from Qaptu.
Partner channel
Build your reseller and referral channel: you set the terms, your partners work in their own area of your brand's website, and you see every sale and every commission. Partners join only through your invitation link.
Tell us what you sell and how you charge for it today, and we will walk you through it.
