Custom Software for Agencies
The software your agency runs on, built by people who came up in the agency world.
Agencies are great at marketing. The software underneath it, the client dashboards, the white-label portals, the internal tools that track margin and capacity, is where it gets held together with spreadsheets, Zapier, and a Looker Studio report nobody fully trusts. We build the custom version your agency owns, from a team that ran an agency and shipped a marketing-measurement platform of its own.
Where it breaks down
The part of the agency nobody built software for.
You sell results. Behind the results is a stack you assembled out of whatever was available, and at a certain size it starts costing you more than it saves.
- The monthly client report that takes a day to assemble from six browser tabs.
- A white-label dashboard that almost matches your brand, with a per-client fee that climbs as you grow.
- Margin and capacity living in a spreadsheet only one person fully understands.
- Zapier holding the stack together, breaking quietly, usually right before a deadline.
- A proprietary process you can't productize because there is no software behind it.
None of this is a crisis on its own. It adds up into hours you can't bill and a business that depends on tools you don't own.
What we build
The software agencies can't buy off the shelf.
MosierData builds custom software for marketing agencies: white-label client dashboards, client portals, internal ops and margin tools, and martech-stack integrations, built around your methodology and owned by you. The things you can't buy off the shelf and don't have time to build in-house.
Client reporting dashboards
Real-time, white-labeled to your brand, pulling from every ad platform, analytics, the CRM, and call tracking into one view your clients actually trust.
White-label client portals
Clients log in to see their campaigns, deliverables, and results under your name, not a vendor's. No per-client fee climbing as you scale.
Internal ops and margin tools
Project, resource, and capacity planning, plus per-client profitability you can see in real time instead of reconstructing it in a spreadsheet every quarter.
Martech-stack integrations
Get the ad platforms, CRM, billing, and project tools talking, so the same numbers stop getting exported and re-keyed by hand. See custom software integration.
Attribution and measurement
Tie every dollar to the lead it produced, across digital, search, social, and offline. This is exactly what we built ROI Insights to do.
Productized tools and SaaS
Turn your proprietary process into software you own: a moat, an upsell, or a product line of its own. Some agencies start with an internal tool and grow it into a product.
Why not the generic tools
AgencyAnalytics and Looker Studio are fine, until they aren't.
The off-the-shelf reporting tools are a smart, cheap start. They stop fitting at a specific point, and it is usually the same three reasons.
Keep the generic tool when
- Your reporting is fairly standard and the templates fit.
- You have a handful of clients and the per-client cost is small.
- A vendor logo on the dashboard does not cost you anything.
Build custom when
- Your reporting is your methodology and your brand.
- Per-client pricing climbs faster than the accounts grow.
- You need a view, a rule, or an integration the tool can't produce.

Proof
We didn't just build dashboards for clients. We shipped our own.
ROI Insights is a marketing-measurement platform we built and run in production. It tracks every marketing dollar across every channel, from digital and search to social and even direct mail and yard signs, then ties each lead back to the source that produced it. It answers the question most agencies get asked and dread: which spend actually generated revenue.
It installs anywhere, does AI call recording and lead scoring, and handles dynamic number tracking and attribution. The point for you is simple: this is the kind of software we build, and we have already built it for the marketing world.

Who's building it
We know the agency world from the inside.
Jim ran a marketing agency for years and was a member of the Seven Figure Agency Mastermind back when marketing services were the business. We are not outsiders guessing at what an agency needs. We have lived the client reporting, the margin math, and the scramble before a renewal, and we build the software that takes that weight off.

Common questions
Questions agencies ask.
What kind of software do you build for marketing agencies?
We build the custom software a marketing agency runs on but can't buy off the shelf: white-label client reporting dashboards, client portals, internal ops and margin-tracking tools, martech-stack integrations, attribution and measurement, and proprietary tools you can turn into a product. Everything is built around your methodology, branded as yours, and owned by you, with no per-client fees.
Do you do our marketing for us?
No. Marketing is your craft, not ours. We build the software underneath it: the dashboards, client portals, internal tools, and integrations your agency and your clients run on. We came up in the agency world, so we build software that fits how agencies actually work.
Can you white-label the dashboards and portals under our brand?
Yes. Everything we build for you is yours, under your brand, with no vendor logo and no per-client fee. That is one of the main reasons agencies move off the generic reporting tools.
We already use AgencyAnalytics, Databox, or Looker Studio. Why build custom?
Use them as long as they fit, and for a lot of agencies they do. They stop fitting when your reporting becomes your methodology and your brand, when per-client pricing climbs faster than the account grows, or when you need a view the tool simply cannot produce. Custom is your data, your brand, owned outright, with no per-client fee.
Can you turn our proprietary process into a product we can sell?
Yes, and it is some of our favorite work. We build the software behind your process so it becomes a moat, an upsell, or a product line you own. Some agencies start with an internal tool and grow it into a SaaS.
How much does it cost, and do we own it?
Most projects start under $10,000. More complex builds with several integrations or larger scope generally run $25,000 to $75,000 or more. We quote one fixed price after a scoping call, before any money changes hands. You own the source code, the data, and the documentation, with no per-seat fees.
