Quick answers
Is Celerp free?
Yes. The desktop app is free for business use: no trial, 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, double-entry 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 and e-commerce, jewelry, gemstones, watches, coins, fashion, cosmetics, food and beverage, wine and spirits, agriculture, electronics, auto parts, hardware, furniture, books and media, art, manufacturing, consulting, SaaS and software, and nonprofits, clubs and associations.
What does Celerp Connect cost?
$29 a month or $290 a year for your whole setup, never per user, with a 14-day free trial. 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 and gifts in another, and at year end the treasurer reconciles both by hand.
Renewals slip through
Each membership is an annual agreement with its own renewal date. Celerp shows who is current, who is in their grace period and who has lapsed, and bills each renewal when it falls due.
Gifts get mixed up with dues
Dues, event tickets and donations can share one invoice, and each line posts to its own income account. Donor histories count only the gifts you received and kept, so refunds and chargebacks drop out.
Restricted money gets spent twice
Turn on funds and every journal line carries one: unrestricted, or a named restricted fund. Money leaves a restricted fund only through a recorded release or reallocation. The fund report reconciles to the books.
The member and the payer are different people
A parent pays for a junior member. An employer pays for its staff. Celerp keeps the member and the payer as separate contacts on the same membership.
Set up in an afternoon
Install free
Download the desktop app, or pip install celerp on a server. Pick the Nonprofit preset at setup and the membership, donation and event ticket items are ready to use.
Add members and their renewals
Add each member with their tier and payer. Annual members renew on their own date; lifetime members pay once.
Bill, record and report
Bill what is due, record bank payments or send a pay link, and send donor statements for any period when you choose.
Built for how members and donors pay
One set of books for dues, gifts, tickets and grants.
Annual or lifetime, with grace days before a membership counts as lapsed.
Every gift a donor gave, whether it came on an invoice or straight into the bank, with dated partial receipts.
Preview a statement for each donor for any period, then send it once you confirm. Each send is recorded.
Restricted and unrestricted funds on every journal line, with releases, transfers and a year-end close that keep each fund in balance.
Get paid the way members pay
Bank transfers, pay links and your accountant's software.
Record bank payments against the invoice, in full or in part.
Connect your Stripe account and each invoice gets a Pay button. The money goes straight to your Stripe account.
Your accountant keeps their software; Celerp Connect syncs the books.
Turn on unattended billing for a membership and each renewal invoice is created on its bill date. It stays off until you turn it on.
Pay links cost 1% plus Stripe's processing fee on each paid invoice. Accounting sync, remote access and backups come with Celerp Connect ($29/mo, flat). The app itself is free.

Questions nonprofits and clubs ask
Is Celerp really free for a nonprofit or club?
Yes. The app is free to use for any number of members, donors and invoices, with a source-available core and open-source modules. Celerp Connect is optional, at $29 a month, for sync, remote access, an AI assistant and backups.
Are donor statements tax receipts?
No. A donor statement lists the gifts a donor gave and you received. What an official receipt must say depends on your country's rules, so check with your accountant before you use a statement as one.
Can it keep restricted grants separate?
Yes. Turn on funds in the accounting settings and every journal line carries a fund. Spending from a restricted fund is backed by a release that records its reason, and the fund report reconciles to the ledger.
Can a parent or an employer pay for someone else's membership?
Yes. Each membership names the member and the payer separately. The invoice goes to the payer, and the membership stays with the member.
Is our member data private?
Yes. Celerp runs on your own computer or server, so member and donor records stay with you. Nothing is stored on our servers unless you turn on Connect backups, which are encrypted.
