Constancia, an EPM consultancy, is an official Abacum partner with certified consultants in the UK.
Bring actuals, assumptions and plans together so you can answer what changed, model what comes next and keep leaders moving from the same numbers.
Actuals, assumptions and plans live in different places. You waste valuable time rechecking numbers and remapping systems.
A pricing change, new hire plan or organisation shift triggers hours of rework, or a systems project that disconnects plans from real decisions.
When you can't give trusted answers in minutes, leaders move on instinct and finance becomes a back office historian.



Abacum (FP&A software) holds a finance team's budget, forecast, headcount plan and scenarios on 1 model and takes actuals in from the ledger. A finance team buys it when the budget workbook has stopped agreeing with itself. Constancia is an EPM consultancy and an official Abacum partner, with certified consultants based in the UK.
Abacum connects to more than 700 source systems, so the actuals arrive in the plan without an export and the forecast moves the same afternoon the ledger does.
The platform is built for the plan, so intercompany eliminations, currency translation and the statutory group result stay with the consolidation. Abacum assumes the consolidation is settled and the plan is the thing that has outgrown its workbook.
Where 3 country finance leads each keep a headcount tab, the group forecast carries 3 salary assumptions. The FP&A manager then reconciles the 3 by email on the last Friday of the month.

Where 2 of the 6 have started to disagree with each other in the workbook, the licence starts to pay back.
Top down and bottom up revenue forecasts sit in 1 model with the quotas and the capacity that produce them.
Budgeted roles, open roles, forecast changes and approvals sit in 1 place, and headcount is usually the first tab a workbook loses control of.
The budget goes down to supplier level on a model that rolls forward each cycle rather than being rebuilt.
A scenario branches off the base version, and the lines downstream of the change update themselves.
Actuals arrive from the ledger onto the same dimensions as the plan, so budget against actual needs no export.
Abacum connects to more than 700 source systems, and the survey tests what each source in your estate will release.
Headcount is where a workbook usually breaks first, because more people edit that tab than any other.
Abacum needs little configuration, so the work moves from building the model to agreeing the drivers with the people outside finance who own them. The survey settles those drivers before the build starts.
A planning model that its implementer alone can change is a subscription to that implementer. We build so an FP&A analyst can add a driver, branch a scenario and change a hierarchy without calling us.
The platform holds SOC 2 Type II, ISO 27001 and GDPR compliance, so the security review runs alongside the build rather than ahead of it.
Finance changes the model the same afternoon rather than raising a ticket, so a cycle that used to wait on a queue runs when the team is ready.
The actuals arrive through the connector and the report reads them where they land, so nobody spends the first week of the month moving numbers between files.
The plan and the actuals share 1 set of dimensions, so the comparison is a subtraction rather than a mapping somebody maintains.
Constancia implements the platform and still points a group elsewhere where the structure has no use for it.
Where the fit fails, we say so on the first call rather than in a proposal.
Constancia implements both, so every row compares the 2 platforms by structure.
| Abacum | OneStream | |
|---|---|---|
| What it is for | FP&A: the budget, the forecast, headcount and scenarios. | The close, consolidation, planning and reporting of a group on 1 model. |
| Who it suits | A finance team whose budget workbook has stopped agreeing with itself and whose consolidation works. | A multi-entity group with several ledgers and a legacy consolidation on a sunset path. |
| What it replaces | The budget workbook, the headcount tab and the scenario copy saved under a new name. | HFM, BPC or IBM Controller and the workbooks around them. |
| Time to live | Weeks, on drivers the business has agreed to own. | Months, because the new close is proved against the old one before cutover. |
| Where it stops | Abacum is built for the plan, so a group with an elimination problem reads the other column. | A single entity with a straightforward close gets no return from OneStream. |
Abacum quotes each licence per group, and 3 things move the figure: the count of planning users, the modules taken and the term length. A finance director comparing 2 quotes lines those 3 up first.
The implementation is a separate cost from the licence, and Constancia prices it after the survey of the workbook rather than before. The price is then fixed, so a driver dispute found in week 3 is already in it.
Where a finance director wants a figure to plan against before the survey, we say what we have seen on comparable Abacum builds.
Each of the 3 is priced after the survey, and the consultants who did the survey carry it through to handover.
Certified UK consultants survey the drivers, fix the price, build the model and hand it to finance.

Read about FP&A consultingThe 6 come from what Google reports against Abacum's own search results, and a firm that implements the platform answers them.
Abacum quotes each licence per group, and the figure moves on the count of planning users, the modules taken and the term length. Constancia prices the implementation separately, and that price is fixed once the survey of the model is done.
Abacum comes from the counting frame called an abacus, chosen as a reference to arithmetic rather than as an acronym.
Julio MartÃnez is the chief executive, and he co-founded the company with Jorge Lluch. Abacum is a Spanish company with an office in New York, and it sells into the UK and Europe.
The model that reads the finance team's own planning model directly performs best, and on Abacum that is Abacum Intelligence. A general chatbot given a spreadsheet export cannot trace a figure to the ledger it came from, so an analyst cannot check its output.
No, Abacum plans and the consolidation stays where it already runs. A group whose problem is intercompany eliminations, currency translation and a group result tied to local books needs OneStream (EPM software) or its like. Constancia says so on the first call.
An Abacum implementation runs in weeks rather than quarters, and the length depends on how settled the planning drivers are. Where the business outside finance has already agreed to own headcount, pipeline and volume, the build is short.
