Back-Office Suite

Why this suite

The back office is where a small company quietly rents four subscriptions for four kinds of paper: the invoices it sends, the spend it approves, the suppliers it vets and the permits it must renew. Each tool is small; together they are a standing monthly bill and four places the same names and dates get typed.

• Invora: invoices and estimates with penny-exact totals, PDF and email, a client's own link to pay by.
• Approva: purchase approvals with segregation of duties — nobody approves their own request, in the browser or through the API.
• Supplia: the supplier register — contacts, documents, expiry dates, the questions you asked before you signed.
• Permora: permits, licences and certificates with renewal reminders, so the one that lapses is the one you knew about.

Four standalone installs, four separate databases, one order and one price. Each app keeps its own MCP endpoint with scoped keys, so an assistant can read the supplier file or draft an invoice without being able to approve anything.

Who this is for: a company of five to fifty that pays for invoicing, spend approval, vendor management and compliance tracking as four subscriptions today, and would rather own the set. Who should keep renting: a business that needs full double-entry accounting or a procurement platform with catalogue and punch-out — these are the operational records, not the general ledger.

Honest limitations — the whole suite

Each product's own limits apply unchanged when it arrives as part of the suite.

Invora — Invoicing & Billing System (PHP + MySQL, Self-Hosted)

• Invora never processes cards. Bring your own payment link (Stripe Payment Link, PayPal.me, your bank's page); payments are recorded here when they land.
• Not double-entry accounting, a general ledger or an ERP — it exports clean CSV/JSON for whatever keeps your books.
• Single-tenant: one business per installation.
• Email goes through your own SMTP server; there is no relay and no sending service.
• Nothing is emailed automatically — every client email is a button a person presses.

Approva — Self-Hosted Purchase-Order Approvals: Requests, Approval Chains, Numbered POs

• Not an accounting system or ERP; it does not post to a general ledger.
• It does not process payments — Approva approves requests and issues POs; it never moves money or pays vendors.
• No 3-way matching (PO ↔ goods receipt ↔ invoice), no inventory, no budgeting or encumbrance accounting.
• No punchout catalogues or supplier portals — a request describes the purchase in your own words.
• One currency per installation (pick any at install — EUR, GBP, AUD, CAD, CHF and more are formatted natively).
• Single-tenant: one organisation per installation.

Supplia — Supplier Register & Contract-Renewal Tracker (PHP + MySQL, Self-Hosted)

• Single-tenant: one company per installation.
• Not a contract-lifecycle suite: no redlining, versioning, approval routing, clause library or e-signature. It files the signed thing and watches the dates around it.
• No accounting or payment integration; values and payment terms are recorded text and numbers.
• Cross-currency contract values are never summed — the value currency is one business-wide display setting.
• Uploaded documents live on your own server: type decided by the file's bytes, generated filename, 10 MB cap, served only through a permission-checked route.
• The calendar feed's URL is its credential: stored hashed, revocable, carrying no contact details and no contract values.

Permora — Permit & Inspection Tracker for Trades (PHP + MySQL, Self-Hosted)

• One company per installation; your team shares it with roles.
• Permora records what staff enter — no AHJ portal, e-permitting, filing or payment integration. That is exactly why there is no filing, payment or e-signature surface on your server to secure.
• Fee totals are single-currency by design; cross-currency sums are never shown.
• Attachments are PNG, JPEG or PDF up to 10 MB, checked by content, served only to a signed-in user through a controller.
• Calendar feeds are read-only and per-feed revocable; changes are made in Permora.
• Not legal advice: whether a permit is still valid is a question for the authority that issued it.
