Invoices that meet local tax rules
Invoices that follow each country's rules, such as Verifactu in Spain and the e-invoicing mandates across Europe.
You stay in control
Your invoices. Your payments. Your customers.
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.
It does not sell on your behalf
You sell to your customers under your own name and your own brands, on your own websites. Every invoice is issued by your company.
It does not handle your money
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.
It does not chase your customers
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.
Compare approaches
The right platform depends on what you want to remain yours
These products overlap, but they are built around different jobs. This comparison uses each company's public product information and focuses on the choice a software maker is really making.
Platform Operating model Best fit What you are choosing
-
Operating model
Infrastructure for software makers that sell in their own name, on their own branded channels and through partners.
Best fit
You want plans, usage, invoices, service access and a reseller or referral channel to share one source of truth.
What you are choosing
Your company remains the seller. Customers and money stay in your relationship and your payment accounts.
-
Operating model
An ERP that brings invoicing, accounting, banks, CRM, projects and other business operations together.
Best fit
A small or medium business wants to run its own back office and accounting from one application.
What you are choosing
You are choosing business-management software; embedding a commercial system inside your own SaaS is a different job.
-
Operating model
Tax calculation, compliant invoicing and reporting connected to the sales channels and payment processors you already use.
Best fit
International tax compliance is the main gap in an otherwise established sales and payments stack.
What you are choosing
It complements your commerce stack; subscriptions, service access and partner operations may still live elsewhere.
-
Operating model
Recurring and usage-based billing built into Stripe's payments platform, with invoicing, a customer portal and entitlements.
Best fit
Stripe is already central to your payment stack and you want billing close to payment processing.
What you are choosing
You get a broad payments ecosystem; your own white-label sales and partner operating model still needs deliberate architecture.
-
Operating model
Subscription, usage and hybrid billing with entitlements, revenue workflows and integrations for growing SaaS companies.
Best fit
A scaling SaaS business needs deep monetization and revenue operations across a mature toolchain.
What you are choosing
You are adopting a broad revenue stack, with the implementation scope and operating model that comes with it.
-
Operating model
A Merchant of Record for SaaS that takes responsibility for payments, recurring billing, tax and compliance.
Best fit
You prefer to outsource the legal seller, payment and global tax burden through one provider.
What you are choosing
Paddle becomes the seller of record. That removes work, but it is fundamentally different from invoicing customers in your own company's name.
Product scopes change. Check each provider's current documentation before deciding.
How it works
From plan to paid, without writing billing code
- 1
Set up your plans
Describe your product and its plans: a flat fee, a price per seat, a price per unit of usage, or a mix. Make a plan public or keep it private for chosen customers and partners.
- 2
Sell direct or through partners
Show live prices with the right VAT on your own website, and let customers sign up on your white-label channel. Partners can resell or refer you under an agreement you both accept.
- 3
Bill every month, in your name
A monthly billing run prepares your invoices, issued by you with gapless numbering: in advance or at the end of the period, with partial months prorated. When one goes unpaid, the service moves through grace, restricted and suspended, and is active again the moment it is paid.
- 4
Your software asks what is allowed
One API call tells your app whether a customer is active, in grace, restricted or suspended, and webhooks tell it when something changes. New subscriptions set up your service automatically, or wait for your team's approval first: you choose.
Plans and prices
Price it the way your product is used
Combine a base fee, a price per seat and a price per unit of usage in the same plan, billed monthly or yearly, in advance or at the end of the period. Qaptu adds it up every month and prepares the invoice in your name.
- Flat, per-seat and usage-based prices, with included quantities
- Public plans for your website, private plans for chosen customers and partners
- Prepaid or postpaid per plan; usage always billed after it happens
- Start or cancel mid-month and pay only for the days used
- Prices are never edited in place: add a new one and archive the old

The right VAT for every buyer, from one call
Your website asks for your prices with the buyer's country and whether they are a business, and gets them back with the right VAT already applied. The endpoint is public, so any website can call it.
- Buyer in your own country: your local rate
- EU consumer in another country: the rate of their country
- EU business with a VAT number: reverse charge
- Buyer outside the EU: no VAT

Unpaid invoices
Know who is overdue, and let your software react
When an invoice is overdue, the service moves through grace, restricted and suspended on the schedule you choose, and is active again the moment the invoice is paid. Your software only has to read the state. How you follow up with your customer is up to you.
