For Perfex CRM 3.4 · Ledger · Bills · Banking · Multi-currency · Tax · Reports
Perfex Books is real double-entry accounting inside Perfex. Invoices, payments, credit notes and expenses post themselves to a chart of accounts you control; add vendor bills, import bank statements and reconcile them, and read a profit and loss, balance sheet and cash flow that always tie back to the documents behind them.
Why Perfex Books
Perfex sends the invoices and records the payments. The books then live in a spreadsheet or another app, re-typed every month, and never quite agree. Books keeps them where the documents already are.
Hours a month, and a mistake in every batch.
With Perfex BooksInvoices, payments, credit notes, refunds and expenses post automatically to the accounts you mapped, each journal linked to its document. Existing history is imported once, from a date you choose, after a preview that checks the totals against Perfex.
The report you sent the bank no longer matches.
With Perfex BooksPosted entries never change. An edit or cancellation adds a reversal and a new entry, and a locked period stays locked: the correction lands on the first open day, linked to the original date.
Ticking statement lines against payments by hand.
With Perfex BooksImport the statement, accept the matching suggestions, let rules handle the bank fees and reconcile to the statement's closing balance. If a later posting changes reconciled history, Books tells you.
What is inside
Every part writes balanced journal entries to the same general ledger, so the reports, the statements and the bank always agree.
The ledger
Every posting is a balanced journal entry — debits equal credits, in the document currency and in your base currency — written in one database transaction. Money is stored as exact decimals, never floating point.
| Account | Debit | Credit |
|---|---|---|
| 1200 Accounts Receivable | 1,080.00 | |
| 4000 Sales Income | 1,000.00 | |
| 2200 Sales Tax Payable | 80.00 | |
| Invoice INV-000214 | 1,080.00 | 1,080.00 |
Chart of accounts
Start from a generic small-business template or a service or product variant, then add, rename and archive accounts. Types and sub-types drive the reports: assets, liabilities, equity, income, expenses and cost of goods sold.
Automatic posting
Choose a go-live date and map once: income per item or item group, a bank or undeposited funds per payment mode, an expense account per category, a tax account per Perfex tax. From then on Books posts by itself through the Perfex cron.
QuickBooks Online and Xero
Connect a QuickBooks Online company or a Xero organisation with your own app keys. Books sends what you do in Perfex, waits politely when the provider says slow down, and asks before it touches anything it is not sure about.
Vendors and bills
Record vendor bills with lines, tax, due dates and the PDF attached. Pay them in full or in parts from any bank account, apply vendor credits, and see aged payables at a glance.
Banking and reconciliation
Import a statement from your bank, check the preview, and match each line to what Books already posted. Suggestions use amount, date, reference and party; rules post the recurring lines for you.
Multi-currency and tax
Invoice in euros, get paid in euros, report in dollars. Books keeps both amounts on every line and works out the difference when the money arrives.
A dated exchange-rate table with each currency's own precision. Rates are never guessed: a missing rate stops the posting and tells you.
Realised gain or loss on settlement; optional period-end revaluation of receivables, payables and foreign bank accounts, reversed on the next day.
Perfex taxes mapped to tax accounts. Collected against paid per rate and period, accrual or cash basis, with drill-down; closed tax periods stay closed.
Reports
Pick a period, compare it with another, filter by customer, vendor, project or cost centre, and click through to the journal and the Perfex document behind it.
Journals and adjustments
Balanced entries with dimensions and attachments. Entries above an amount you set wait for another person to approve them.
Depreciation or rent every month through the cron; accruals that reverse themselves on the date you choose.
Lock dates, fiscal year close with retained earnings, and an audit log of every posting, reversal, reconciliation, close and settings change.
Switching from another accounting module
Already keeping accounts in another Perfex accounting module? Books reads it on the same database — it never changes a thing in the old module — and shows you what it will import before it does.
Read-only by design. The old module's tables are only read. Past bank reconciliations come across as reference; you reconcile fresh statements in Books.
Integrations
Invoices, payments, credit notes, refunds, expenses, subscriptions, taxes, payment modes, customers, projects, staff permissions and the cron.
Each approved pay run posts one payroll journal — gross pay, deductions, net pay and employer costs — and adjustments post their difference.
Stock value and cost of goods sold from Product Hub; commission and loyalty accruals from Sales Growth, each posted once.
Seven widgets for your dashboards: cash, profit, receivables, payables, the profit trend and receivables and payables ageing.
Ask “What was our profit last quarter?” or “Which bills are overdue?” — answers from the same ledger, within each person's rights.
Accounts, journal entries and reports as read-only API resources for your other tools.
Actual results from the ledger next to your forecasts.
Each workspace keeps its own books; nothing is written inside the module folder.
Security & control
Separate Perfex permissions for viewing, reports, drafting, posting, approving, reconciling, closing periods and settings. Staff without View see nothing of Books at all.
Activate Books, choose a starter chart of accounts and set your fiscal year and lock date.
Map payment modes, expense categories and taxes, enter opening balances and choose the go-live date.
Preview the backfill from the date you want, compare it with Perfex's totals and confirm.
Roadmap
What we are building and planning. Plans can change, and we never promise dates: an item ships when it is ready and tested.
Statements straight from your bank instead of a file, through a feed provider.
Update the module from the Perfex admin, with a backup first and a way back.
Pricing
Perfex Books
$159one-time
One installation, unlimited staff, accounts and transactions. Licence and support terms are shown on the SellMyCode listing. No per-user fees. Sold by SellMyCode.
Buy on SellMyCode Read the documentationInterface in nine languages. Requires PHP 8.1 with BCMath. Books keeps accounting records; it does not file tax returns or move money.
No. It gives you and your accountant clean, balanced books inside Perfex, with every number traceable to a document. Year-end judgement and tax filing stay with your accountant.
Nothing until you choose. Books posts new documents from your go-live date. To bring in older ones, run the historical backfill from a start date: it previews every document, compares the totals with Perfex's and only posts after you confirm.
Books adds a reversal and a new entry. The original entry stays, so the audit trail is complete. If the date is in a locked period, the correction posts on the first open day and keeps a link to the original date.
Not in 1.0. You import statements as CSV, OFX/QFX or CAMT.053, which every bank offers. Books has a hook for live bank-feed providers later.
Yes. Connect either with your own free developer app keys; Books sends customers, invoices, credit notes, payments, refunds and expenses, keeps edits and cancellations in step, and shows payments recorded there for review. You can use the Books ledger, the accounting app or both.
No. You create a free app in the Intuit or Xero developer portal, paste its keys into Books and sign in once. Your tokens stay encrypted in your own Perfex database; nothing passes through our servers.
Every line keeps the document amount and the base amount at the rate of that date. Settlements post realised gains and losses; a period-end revaluation is optional. A missing rate stops the posting rather than guessing.
No. It gives you a tax summary per period — collected against paid, per rate and tax code, accrual or cash — that you or your accountant file. Country e-filing is out of scope.
Staff need Books View to see anything. Reports, drafting, posting, approving, reconciling, closing periods and settings are separate permissions. Report totals are company-wide; document names and links follow each person's own Perfex customer and project rights.
No. Books uses Perfex's module hooks and its own tables. Deactivate it and posting stops; your books stay until you remove them.
Perfex CRM 3.4 or newer (tested on 3.4.1), PHP 8.1 or newer with BCMath, MySQL or MariaDB with InnoDB, and Perfex's cron job.
Yes. The interface ships in English, Spanish, Portuguese (Brazil), French, German, Italian, Dutch, Turkish and Russian, with standard accounting terms in each.
Yes: the live demo runs Books with fictional data. Sign in as the admin demo account shown on the login page (demo@perfexcrm.app, password demo1234). Settings, uploads and anything that sends e-mail or connects to an outside service are switched off there, and the data resets every few hours.
Contact us through sellmycode.net. Six months of support are included with every licence. Please add the module, Perfex and PHP versions and a screenshot — never passwords or secrets.
Automatic posting, bills, bank reconciliation and reports that tie back to every invoice.
