Mortar vs Gather for interior design studios

Gather and Mortar both put the FF&E list at the centre of the project, so they get compared more than their customers overlap. Gather is built for commercial and hospitality FF&E teams: specification packages, issued revisions, purchasing and shipment tracking at the scale of a hotel or an office fit-out, with Studio McGee among the firms on its homepage. Mortar is built for residential studios that need the budget, the schedule, the client's approvals and the orders on one list the client can open.

If you issue 300-line specification packages to a general contractor, read Gather's side carefully. If you're a studio of one to ten people running homes, read ours.

Quick verdict

Choose Gather if your work is commercial or hospitality FF&E, you issue formal spec packages with revision control to contractors, and you want an API or AI agents working across hundreds of items. Choose Mortar if you run residential projects, your client needs to see the budget and approve selections without a login, and you want invoicing and payments in the same place as the orders.

A closer look at Gather

Gather makes "everything your team needs for complex FF&E work". The workflow runs from the web clipper to specification, to issued packages with revision control, to budgeting and, on Core Plus, purchasing and delivery tracking. It is unusually open: a public API, MCP access on both plans so Claude or ChatGPT can work directly in a Gather workspace, and AI agents that run checks and reports across a project. Its own comparison post pits it against DesignSpec, Specsources and Fohlio, which tells you the market it's in.

Pricing on the site is annual: Core at $228 a month and Core Plus at $276 a month, each with five seats included and extra seats at $31 or $36. Annual billing is 30% off the monthly rate, and Gather's own comparison post puts monthly billing from $199 with one seat. New customers get 25% off the first year. There is no self-serve trial; you book a demo and the trial follows.

Where it stops, by its own site: Gather doesn't list client invoicing or client payments, describes itself as "not an accounting, invoicing, or time-billing system", and its client approval flow is built around issued specification packages rather than a running portal. For a residential studio that bills the client for product, that half of the project happens elsewhere.

  • You're a studio of one to ten people and don't want a five-seat minimum or a demo to start

  • Your work is commercial or hospitality FF&E at the scale of a hotel or an office fit-out

Frequently asked questions

Is Gather for residential designers?

It can be used that way, but it's built and priced for commercial FF&E teams. Residential studios will find the spec depth more than they need and the price per seat higher than tools built for them.

Do both connect to Claude or ChatGPT?

Yes. Both Mortar and Gather offer MCP access, so an AI assistant can read and update projects. Our earlier blog post called Mortar one of the first in the category to do this; Gather has it too, so we've said so there.

Which is cheaper?

For a studio of one to five people, Mortar: $59 to $295 a month against Gather from $228 a month on annual billing, or from $199 on monthly. For larger commercial teams on Gather's five-seat annual plan the per-seat gap narrows.

The verdict

Different jobs, one list each

The client is in the room with Mortar: they open the project from a link and approve selections where the budget lives, and the invoice comes off the same list as the order. Gather's list is the specification package, issued to a contractor and locked on the date it went out, with purchasing and delivery tracking behind it on Core Plus. If you issue packages to a GC on a hotel, Gather's depth matters more than a client portal. If you run homes and bill clients for product, Mortar is the one built for you, at $59 a seat with no demo in the way.
