TL;DR
Invoice subscriptions auto-generate and auto-deliver invoices to retainer clients on any billing schedule, so the same invoice goes out every week, month, or quarter without manual creation.
Plutio manages subscriptions under Financials with two billing modes: manual billing sends the invoice and lets the client pay on receipt, while auto billing charges the client's saved Stripe card directly on the billing date. Each subscription ties to a subscriber and optionally to a project, keeping billing and project work in one workspace. Freelancers using Plutio subscriptions for retainer billing report saving roughly 2 hours per month on invoice creation and follow-up across a five-client retainer roster.
Subscriptions are available on all Plutio plans starting at $19/month, including the 7-day free trial. Set up takes under 5 minutes per subscription from Financials in the main navigation.
What invoice subscriptions are
An invoice subscription is a billing entity that auto-generates invoices on a repeating schedule and delivers them to a specific client without manual action per cycle.
In Plutio, subscriptions live under Financials in the main navigation. Each subscription has a title, a subscriber (the client), a repeat schedule (daily, weekly, monthly, or yearly with a custom multiplier like every 2 weeks or every 3 months), a start date, a billing type, and accepted payment methods. Once activated, Plutio generates and delivers each invoice on schedule. The subscription tracks every generated invoice with its status (paid, pending, or failed), so the full billing history for that client lives inside the subscription record.
Manual billing subscriptions
With manual billing selected, Plutio generates the invoice on the scheduled date and sends it to the client with a payment link. The client opens the invoice in the client portal, reviews the amount, and pays through Stripe, PayPal, or Square. Manual billing fits retainers where the monthly amount varies or where the client prefers to review and approve each charge. The subscription status stays Active as long as the client pays within the due window. If a payment is overdue, the subscription moves to Past Due and Plutio sends the reminder schedule configured on the invoice.
Auto billing subscriptions
With auto billing selected, Plutio charges the client's saved Stripe card directly on each billing date with no action from either side. The client pays the first invoice manually to save their card and activate the subscription. From that point, each cycle charges the card and sends the client a receipt. If the charge fails, Plutio marks the subscription as Failed, logs the failure reason, and notifies the freelancer so the card can be updated before the next attempt. Auto billing removes both the sending step and the waiting step, so the freelancer's only task is reviewing the occasional failed charge rather than managing every payment manually.

Why invoice subscriptions matter for retainer billing
Without subscriptions, every billing cycle restarts the same manual process: find last month's invoice, duplicate it, update the date and line items, send it, and then wait for the client to pay while sending follow-up reminders.
For a freelancer with six monthly retainers at $2,500 each, that process repeats 72 times per year. At 10 minutes per invoice plus 5 minutes of follow-up per cycle, the total reaches 18 hours of billing admin annually, the equivalent of two full billable days at $150/hour, or $2,250 in lost revenue spent on administrative work that could be fully automated.
FreshBooks locks recurring invoices behind the Plus plan at $33/month, and each FreshBooks invoice exists as a standalone billing event with no connection to a project, proposal, or client portal. Stripe Billing supports subscriptions but adds a 0.7% surcharge on top of standard processing fees and requires API configuration or a developer to set up anything beyond a basic recurring charge.
The gap in most billing tools is that the recurring invoice is disconnected from the work. The invoice fires on schedule, but the client's project status, communication history, and payment record live in three different tools. In Plutio, the subscription ties directly to the project, so billing and work status are visible from the same dashboard.
Plutio's subscription statuses (Active, Paused, Past Due, Failed, Cancelled) turn the Financials dashboard into a retainer health monitor. A Failed status means a card was declined. Past Due means an invoice was sent but not paid within the window. The freelancer checks one screen instead of opening each invoice individually to figure out which client needs a follow-up.
How invoice subscriptions work in Plutio
Create a subscription under Financials, select the client, set the schedule and billing type, and Plutio generates every invoice from that point forward automatically.
Before creating a subscription, make sure the client exists as a contact in Plutio and that at least one payment gateway (Stripe, PayPal, or Square) is connected under Settings.
Step by step
- Step 1: Go to Financials in the main navigation and open Subscriptions. Click Create subscription to open the setup form.
- Step 2: Select the subscriber from your contact list and optionally attach the subscription to a project so generated invoices link to the correct job.
- Step 3: Build the invoice template by adding line items, quantities, and rates. The total becomes the recurring charge amount for each cycle.
- Step 4: Set the repeat schedule under the Schedule section. Choose the interval (daily, weekly, monthly, or yearly) and any multiplier (every 2 weeks, every 3 months). Set the start date for when the first invoice should generate.
- Step 5: Choose the billing type: Subscription (manual billing) to auto-send invoices the client pays on receipt, or Subscription (auto billing) to charge the client's saved Stripe card directly on each billing date. Select which payment methods to accept.
- Step 6: Optionally toggle End subscription and set the number of invoices to create if the retainer has a fixed term, such as a 12-month contract. Click Create subscription to activate.
For auto billing, the client pays the first invoice manually to save their card. From the second cycle onward, Plutio charges the saved card and sends a receipt automatically.
Who needs invoice subscriptions
Any freelancer or agency billing at least one client on a monthly retainer gets immediate value from invoice subscriptions, particularly virtual assistants, social media managers, SEO consultants, and agencies running ongoing support contracts.
A virtual assistant billing five clients at $1,500/month used to rebuild five invoices on the 1st of every month. With subscriptions in Plutio, all five generate and send automatically. On auto billing with Stripe, the client's card gets charged and a receipt arrives without the VA opening Plutio. Across 12 months, that eliminates 60 manual invoice builds and saves roughly 10 hours of billing admin per year. At a $50/hour billing rate, the time saved is worth $500 annually, more than covering Plutio's Core plan at $19/month.
Agencies managing 10 to 20 retainer clients at $3,000 to $5,000 per month see the return multiply. A 15-client agency on Plutio's Pro plan at $49/month generates 180 invoices per year without manual creation. The team reviews only subscriptions showing Past Due or Failed statuses instead of checking every invoice across the client list. Each subscription links to the client's project, so account managers see billing status and project progress from the same view.
Freelancers exploring FreshBooks alternatives often switch because FreshBooks recurring invoices are standalone billing events with no project, proposal, or portal connection. Stripe Billing handles the payment processing but provides no project management, no client portal, and no proposals, so freelancers using Stripe for recurring billing still need separate tools for the rest of their workflow. Plutio handles the subscription, the project, the proposals, the contracts, and the client portal in one workspace at one price.
Bottom line: any freelancer billing the same client the same amount on a repeating schedule should use a subscription instead of manually creating invoices each cycle. Two retainer clients on auto billing pays for Plutio in saved admin time within the first month.
