Self-Hosted Invoicing
Every SaaS invoice you send lives in someone else’s database, behind someone else’s login, on someone else’s pricing page. Self-hosted invoicing flips that: the software runs on your server, the data sits in your database, and nobody can raise the rent or sunset your plan. Here’s the honest case — including what self-hosting costs you, and the shortcut most comparisons miss.
Why self-host your invoicing
- Data ownership. Client records, amounts, payment history — this is business-critical data. In your own database it’s queryable, backupable, exportable, yours. In a SaaS it’s an export button the vendor controls, formatted how they choose, available while your subscription is current.
- No subscription decay. SaaS invoicing runs $19–$65/month per user, forever (FreshBooks, June 2026 — with the $19 tier capped at five clients). Self-hosted software costs what your hosting already costs.
- No lock-in, no surprises. Vendor gets acquired, sunsets your plan, doubles the price? Your invoicing doesn’t notice.
- Your domain, your brand. Clients pay at your-domain.com — not vendor.com/your-account with someone else’s logo in the corner.
What you give up (the honest part)
Self-hosting means the operational side is yours: backups, updates, uptime, SSL. The classic dedicated self-hosted apps — Invoice Ninja, InvoicePlane, SolidInvoice, Akaunting — are genuinely capable, but each wants its own server or container, its own database, its own update cadence, its own security patching. That’s a real systems-administration commitment, and it’s where most “I’ll self-host it this weekend” plans quietly die. If you’d enjoy running a Docker stack for your billing, those tools deserve a look. Most freelancers and agencies wouldn’t.
The WordPress shortcut
Here’s the move the self-hosting roundups miss: if you run a WordPress site, you already self-host. The backups, updates, SSL, and uptime questions are already answered — by your host or your existing routine. Adding invoicing to that stack isn’t a new server; it’s a plugin install. Same database you already back up, same domain your clients already trust, zero new infrastructure.
That’s precisely what DuePress is: self-hosted invoicing with the operational cost of a WordPress plugin. Invoices and client records in your WP database. Payments flow from your client’s card through your own Stripe or Square account to your bank — no middleman ever holds your money. Deposits, partial payments, overdue reminders, PDF, activity log: all of it free, no per-invoice fees.
Self-hosted options compared
| Route | Infrastructure you manage | Cost | Best for |
|---|---|---|---|
| WordPress + DuePress | The site you already run | $0 (Pro $79/yr) | Anyone with a WP site |
| Invoice Ninja (self-hosted) | Own server/container + DB | Free software + your ops time | Tech-savvy, feature-maximal |
| InvoicePlane / SolidInvoice | Own server + DB | Free software + your ops time | Minimalists who like sysadmin |
| Akaunting | Own server + DB | Free core, paid apps | Wants accounting too |
What you need to start
- A WordPress site (6.4+) on PHP 8.2+ with HTTPS — any decent host qualifies
- A Stripe or Square account for card payments
- Ten minutes: install → connect → send
