One compliant invoice number stream. As many brands and checkouts as you need.
invAIse is the billing backbone for companies that sell under more than one brand, product, or storefront — but still need to hand their accountant one clean, unbroken, tax-compliant invoice sequence.
Currently onboarding a small number of early customers. Reach out and we'll set up your account by hand.
Built for businesses that outgrew "one shop, one invoice book"
If any of this sounds familiar, invAIse is built for you.
Small business owners with more than one brand
You run several storefronts, products, or brand names under one legal entity — and every one of them needs its own logo and checkout, but only one invoice sequence for the Belastingdienst.
Accountants & bookkeepers
Advising clients who sell across multiple brands or platforms? invAIse keeps their numbering sequential and their VAT treatment correct by default, so what lands on your desk is already clean.
B2B companies selling internationally
NL, EU reverse-charge, and non-EU customers are handled automatically — no spreadsheets, no manual VAT lookups, no guesswork on which rate applies.
Every brand gets its own storefront. Your books stay singular.
Customer checks out
Through Stripe, a WordPress site, or a manual invoice — under whichever brand they bought from.
invAIse assigns the number
One unbroken sequence per legal entity, correct VAT treatment applied automatically.
Invoice goes out on-brand
Your logo, your template, your sender identity — the compliance detail stays invisible to the customer.
Bookkeeping syncs
Sent invoices flow toward your accountant's tools, so nothing needs re-entering by hand.
Four storefronts, four brands, four checkouts — one unbroken, compliant invoice sequence coming out the other side.
What's live today, and what's next

Live now🛒 WordPress / WooCommerce replacement
A drop-in WordPress connector so your site's "Buy now" button skips WooCommerce's checkout entirely and goes straight through invAIse — one less plugin to fight with.
On the roadmap📚 Basecone sync
Sent invoices sync automatically into Basecone for your accountant — paid-status sync is planned as a follow-up.
On the roadmap⏰ Automated payment reminders
Configurable 1st/2nd/3rd reminder emails for overdue invoices on net-30 terms, so chasing payment stops being manual.
On the roadmapSimple, per-tenant pricing
