Quick answers
Is Celerp free?
Yes. The desktop app is free for business use: no account needed, no per-user fee and no limits on companies, users, items or records. The core is source-available and the modules are MIT-licensed.
Does it work offline, and can I self-host it?
Yes. Celerp runs on your own computer and works offline: the core product needs no internet connection. You can also self-host it on an office or cloud server, so the database stays on hardware you control.
What does Celerp cover?
Inventory, invoicing, purchasing, full accounting, CRM, manufacturing with bills of materials, and reporting, all sharing one set of data.
Which industries is it built for?
It ships with presets for retail, jewelry, gemstones, watches, coins, fashion, cosmetics, food and beverage, wine and spirits, agriculture, electronics, auto parts, hardware, furniture, books and media, art and consulting.
What does Celerp Connect cost?
$29 a month or $290 a year for your whole setup, never per user, with the first 14 days free before billing starts. Connect adds store and accounting sync, remote access, 100 included AI queries and encrypted cloud backups. The desktop app works fully without it.

Why clubs and nonprofits outgrow spreadsheets
Dues live in one sheet, late payers get missed, and the treasurer reconciles it all by hand.
Who hasn't paid their dues?
Put each member's dues on a recurring invoice with its own billing date. Celerp shows which invoices are overdue, and creates the next one when you bill it by hand, or on schedule once you turn on automatic billing.
The committee wants a report by Friday.
Dues, tickets and other income each post to their own account, so a report is a few clicks, not a weekend of spreadsheet work.

Questions nonprofits and clubs ask
What does it cost a small club?
Nothing to use the app, however many members you add. Celerp Connect is optional, $29 a month, for remote access, sync and backups. Online payments through a Connect pay link cost 1% per payment, plus Stripe's processing fee.
Can volunteers use it?
Yes. Give each volunteer a role, viewer, operator, manager, admin or owner, so they see and do only what their role allows.
Can members pay online?
Yes, through a Celerp Connect pay link, which brokers the payment. Bank transfers work without Connect.
What happens to our data?
It stays with you. Celerp runs on your own computer or server, and your books and member data stay there. When you send a pay link, the Connect relay keeps a record of that payment: its reference and status. If you turn on Connect backups, a copy of your data is kept there as well.
