Open Source ERP
for Dev Agencies
Kovalyn helps software agencies manage projects, clients, scope, timecards, invoices, costs, contractors, and retainers from one connected workspace — without locking your operations inside a closed platform.
Most agencies don't fail at building. They fail at the business behind the build.
Projects live in one tool. Invoices in another. Hours in a spreadsheet. Approvals in email. Profitability lives nowhere.
One source of truth for delivery and finance.
Scope, time, and cost connected by default.
Open source. Self-hostable. Yours.
Not just project management. Agency operations.
Seven connected modules covering the full lifecycle of agency work — from scope and delivery to billing and contractor payouts.
Projects
Delivery with business context
Manage client and internal projects, milestones, phases, tickets, and delivery risk in one operational view.
Learn moreScope & Estimates
Scope as a first-class object
Track scope from estimate to approval to change order, with versioned history and budget-to-scope comparison.
Learn moreTime & Utilization
Know where time is going
Capture billable and non-billable hours, approve timecards, track retainer burn, and see utilization in real time.
Learn moreLedger & Invoicing
Connect delivery to financial truth
Issue invoices, track payments, categorize costs, and see margin and profitability per project and per client.
Learn moreClient Portal
Clarity without internal chaos
Give clients a clean interface for status, approvals, invoices, documents, and requests — scoped to what they need to see.
Learn moreContractors
Track work, cost, and contribution
Manage contractors, subcontractors, and freelancers — including rates, assignments, timecards, and payment status.
Learn moreIntegrations
Connect without surrendering control
Native connectors to the accounting, finance, communication, and developer tools agencies already run on.
Learn moreFrom first lead to invoice paid — connected.
Every step links to the next. Scope informs timecards. Timecards inform invoices. Invoices inform margin. Margin informs the next estimate.
