The Redmineflux Invoice Plugin generates client invoices directly from logged Redmine time entries. Teams currently using manual CSV exports and spreadsheets spend two or more hours per client per billing cycle reconstructing data that already exists in Redmine. The plugin removes that reconstruction step entirely time logged in Redmine becomes a client invoice without leaving the platform.
Most service teams that run Redmine have a billing process that looks roughly like this.
At the end of the month, someone opens Redmine. A time report goes to CSV. Then comes Excel matching entries to the correct client, filtering out internal hours, calculating billable totals, and formatting the result into an invoice template.
If anything does not line up a missing activity tag, an entry on the wrong project they track down the engineer, ask what happened, and wait.
That process takes two hours on a good month. It takes longer when the data is inconsistent. In fact, one team reported spending two full days every month on invoice compilation before switching to the plugin.
Yet here is what makes this painful: the data is already in Redmine. Hours, projects, activity types all of it is already there. Billing from a spreadsheet means rebuilding information that Redmine already holds in a structured, searchable form.
This is not a Redmine limitation. Rather, it is a gap in how time data flows into invoices.
Before we look at the plugin, let us be precise about what the manual process costs.
Time cost per client, per month. A 10-person team with three active clients typically needs two to three hours per client per billing cycle export, clean, calculate, format, review, send. As a result, that is six to nine hours of administrative work that produces no deliverable value for the client.
At a £50 hourly rate, that is £300–£450 spent on invoice assembly every month. In other words, neither billing nor delivery just administration.
Error risk. Manual data transfer creates errors wrong billable totals, hours on the wrong project, an entry marked internal when it was client-facing. Although these rarely cause large disputes, they consistently create friction a client question, a correction request, a delay in payment.
Approval gaps. When invoices are assembled manually from raw Redmine exports, they are built from unapproved time entries. If no timesheet approval step exists, the invoice may include entries a manager would have rejected wrong activity, wrong project, inflated estimate.
No payment tracking. Most teams send invoices by email from a spreadsheet. As a result, payment tracking happens in a separate system or worse, in someone’s inbox. Consequently, the link between the invoice and the Redmine project that generated it breaks the moment it leaves Redmine.
The Redmineflux Invoice Plugin replaces every manual step in that chain.
Time logs already in Redmine no export needed. Instead, the plugin reads time entries directly from Redmine. You select the project, the date range, and the billable activities. The data populates automatically. No CSV, no copy-paste, no reconstruction required.
Project rates and Team Rates applied automatically. Configure a project hourly rate for uniform billing. Or use Team Rate configuration to set individual billing rates per team member on the same project useful when senior and junior developers bill at different rates. The plugin applies the correct rate to each entry without manual calculation.
Customer management built in. A global customer module stores client contact details, billing addresses, payment terms, and invoice history across all projects. Link each Redmine project to its customer once. Every invoice generated for that project picks up the correct client record automatically no re-entering the same details every month.
Invoice generated from a branded template. Select the time entries and generate. The plugin produces a formatted invoice using your configured template logo, client details, line items, and payment terms included. Custom invoice and email templates keep the output consistent across every client engagement.
Draft → Sent → Paid lifecycle inside Redmine. Moreover, the invoice stays in Redmine through its entire lifecycle. Draft while you review it. Sent once dispatched. Paid when the client confirms. Invoices lock after dispatch the billing record is fixed and cannot be edited after sending. Every status is visible from a central invoice dashboard across all client engagements.
Stripe payment links. Configure Stripe credentials once in the payment gateway settings. Every dispatched invoice includes a payment link. Clients pay directly from the invoice email without additional setup on their side. Payment status updates in Redmine automatically. Manual payment recording is also available for teams that prefer offline reconciliation.
| Step | Manual Process | With Invoice Plugin |
|---|---|---|
| Get time data | Export CSV from Redmine, open in Excel | Plugin reads directly from Redmine — no export |
| Filter by client | Manual sort and filter in spreadsheet | Select project and date range — entries auto-populate |
| Apply billing rates | Manual calculation per entry or per person | Project rates or Team Rates applied automatically |
| Calculate billable total | Formula in Excel, verify manually | Calculated automatically from logged entries |
| Manage client details | Rebuilt manually per invoice | Global customer module — configured once, applied always |
| Format the invoice | Copy totals into invoice template | Branded template applied at generation |
| Send the invoice | Email with attachment | Stripe payment link dispatched from Redmine |
| Track payment | Separate spreadsheet or inbox | Draft → Sent → Paid dashboard in Redmine |
| Time per client | 2–3 hours per billing cycle | 10–15 minutes per billing cycle |
| Error risk | High — manual data transfer | Low — data comes directly from logged entries |
Overall, the reduction is not marginal. In practice, a three-client service team goes from six to nine hours of invoice administration per month to under an hour. The saved time goes back to delivery.
Finance Lead: Invoices are built from verified Redmine time data. No spreadsheet reconstruction. No manual rate application. Every line item is traceable to a logged entry billing disputes drop because the evidence is already in the system.
Project Manager: As a result, billing accuracy improves because every invoice line traces back to a specific logged time entry. When a client questions a charge, the answer is a verifiable record, not a conversation.
IT Director: One system of record covers both project delivery and invoicing. Full audit trail. No parallel tools to reconcile or maintain.
Business Owner: Outstanding, sent, and paid invoices are visible from a single dashboard across all client engagements. Consequently, payment status lives in Redmine not scattered across inboxes and spreadsheets.

What is a Redmine billing plugin?
A Redmine billing plugin connects Redmine’s time tracking data directly to invoice generation. Instead of exporting time logs to a spreadsheet and building invoices manually, the plugin reads time entries, applies billing rates, and produces formatted client invoices inside Redmine. The Redmineflux Invoice Plugin handles the full cycle from time entry to Stripe payment without leaving the platform.
Can I generate an invoice from Redmine time entries?
Yes. The Redmineflux Invoice Plugin reads time entries logged against Redmine projects and converts them into formatted invoices. You select the project, date range, and client. The plugin populates the invoice automatically and applies your configured billing rates project-level rates or individual Team Rates per user.
Can I set different billing rates for different team members?
Yes. The Team Rate feature lets you configure individual hourly rates per user on the same project. A senior developer and a junior developer can bill at different rates on the same engagement. The plugin applies each member’s rate to their time entries automatically no manual rate calculation required.
Can I edit an invoice after sending it?
No. Invoices are only editable in Draft status. Once dispatched, the invoice locks and the billing record is fixed. This protects clients from receiving amended invoices after the fact. If a correction is needed, create a revised invoice in Draft and dispatch the new version.
How does Stripe payment work with the Invoice Plugin?
Configure your Stripe credentials once in the payment gateway settings. After that, every dispatched invoice includes a Stripe payment link. From there, clients pay directly from the invoice email. Once payment is received, Redmine updates the status automatically. Teams that prefer manual reconciliation can also record payment manually from the invoice dashboard.
Billing disputes start with bad data. Bad data starts with manual exports.
The Redmineflux Invoice Plugin pulls directly from approved time entries — so every invoice line is traceable, every total is accurate, and every client conversation starts from a verified record.
