Yes. ManyRequests works for agencies that don't sell subscriptions, or only sell a few. You can run hourly work, one-off projects and the occasional retainer from the same portal, without changing how you price your services.

Every service you create is either One-off (charged once for a fixed scope of work) or Recurring (billed every period as a subscription). You choose this in the first step of creating a service, under Services > All services. Nothing forces you to offer recurring services.

When you first set up your portal, ManyRequests also asks How do you typically charge your clients? and suggests starter services for the model you pick: One-off projects, Monthly retainer, Hourly rate or Mixed (varies by service). You can edit or delete these services later.

Create one-time services for work with a defined scope and price, such as website builds, branding projects or campaign work. Clients pay once, submit their requests and you deliver through the portal. See How to create a one-off service.

Sell time-based services as bundles of hours, and let clients buy more hours when they run low with top-up options. Time your team logs on requests is deducted from the client's hours, so you and the client always see what's left.

If you price work per deliverable rather than per hour, sell credit-based services. Each request costs a number of credits, and clients can top up when they need more. See How to create credit-based services.

You can bill clients without any service checkout at all:

If some clients want ongoing work, offer a recurring service for just those clients. See How to create a recurring service.

ManyRequests suits agencies of any size that don't rely only on subscriptions. You can manage one-off projects, hour and credit packages, invoices and the occasional retainer in one portal, while keeping your existing sales and delivery model.
