The wedge
When someone asks where the number came from,
the answer should not be buried in a spreadsheet.
Most PHA finance teams keep the real allocation logic in a workbook that lives on one laptop, with formulas only one person can explain. It works until the auditor asks, the board asks, or that person leaves.
The issue is not just the math. It is the handoff. Who owns the method, who reviewed it, what data was used, what changed, and what support you can show an auditor or your board.
The first step
Start with one allocation cycle.
Most PHAs do not need to start with a giant software implementation. The clean first step is one allocation cycle.
You provide GL and TB exports, your current allocation method, and supporting basis inputs. Synthronix configures the model in Apportix, runs the cycle, and returns the workbook and support package for review.
What you send us
InputsGL detail
Trial balance
Chart of accounts
Current allocation method
Basis inputs (FTE hours, square footage, unit counts)
Prior workbook or schedules, if available
Desired journal-entry output format, if available
Not ready to operate another system? We can run the first cycle for you.
Many PHAs already send data to a fee accountant or consultant and get schedules back. Apportix can fit that same buying pattern at first. You send the GL and TB detail and allocation inputs, Synthronix runs the cycle through Apportix, and your team receives the support package.
The difference is the model is preserved instead of rebuilt from scratch next year.
01
Model setup
We configure your chart of accounts, FDS mapping, cost pools, basis tables, and allocation rules in Apportix.
02
Allocation run
We run the cycle against your GL and TB data and produce the allocation, with every figure traceable to its source.
03
Support package
You get allocation schedules, support detail, and a reconciliation summary built for review.
04
Draft JE output
Draft journal-entry output you can review and use for upload support. We do not post it for you.
05
Review session
We walk your team through the output, the method, and the trail behind each number.
06
Recurring model preserved
The model stays live. The next cycle starts where this one ended, not from a blank workbook.
Deliverables
What you receive.
PHAs buy outputs, not logins. Here is what comes back from a cycle.
Initial allocation cycle package
Per cycleAllocation schedule workbook
Support detail by source, rule, basis, recipient, and FDS line
Reconciliation summary
Draft journal-entry output for review and upload support
Locked run artifacts and explain-this-number trail
Auditor-support packet
Optional read-only auditor access
No direct GL posting and no REAC submission
Not included in a cycle
- Direct GL posting or REAC submission
- An audit opinion
- Full ERP replacement
- Unlimited reruns within one scope
- Quarterly or monthly cycles unless scoped
- ERP migration or remapping unless scoped
Operating model
Choose how much you operate.
You do not have to buy a login and figure it out. Pick the level of support that fits your team today.
We recommend most agencies start done-for-you, then decide how much they want to run internally after seeing the first output.
Already have a fee accountant or consultant?
Good outside help is valuable. Apportix does not require you to fire anyone on day one.
The first step can be simple. Synthronix runs one allocation cycle through Apportix and returns a package your team, accountant, consultant, or auditor can review.
Over time, the agency owns more of the model, support trail, and institutional memory.
Workflow
One predictable loop, end to end.
The same six steps run every cycle, every method, every program. Each step is its own artifact. Versioned, reviewable, and exportable.
01 · Import
Bring in your data.
CSV import for chart of accounts, GL detail, trial balance, and basis tables. Validated on the way in.
02 · Map
Map to FDS.
Map accounts to FDS line items once. Reuse the mapping every cycle, with versioned changes.
03 · Allocate
Run the rule.
Cost pools, basis tables, allocation rules. Every run is a versioned, immutable artifact.
04 · Review
Explain every cell.
Click any number, see the source rows, the basis snapshot, and the rule version that produced it.
05 · Lock
Approve and lock.
Approval workflow with full audit log. Locked runs cannot drift after the fact.
06 · Export
Hand off the packet.
Auditor packets, FDS support exports, read-only auditor access. The handoff stops being a panic week.
Done-for-you Synthronix can operate these steps for you on the first cycle.
Scope
Built around your GL.
Built around your GL.
Not replacing it.
Apportix sits beside Yardi, MRI, Emphasys, PHA-Web, CentralSquare, and the accounting workflow your finance team already uses. It does not post journal entries, replace the general ledger, or submit to HUD on your behalf.
It turns exports, allocation methods, basis data, review steps, approvals, and support files into a traceable workflow your team can defend.
- Organizations, workspaces, fiscal years
- AMPs, programs, chart of accounts, FDS mapping
- Cost pools, basis tables, allocation rules with immutable versions
- Runs, approvals, locks, audit log, read-only auditor access
What Apportix is
- A traceable allocation and FDS support layer
- Versioned cost pools, basis tables, and rules
- Approval and lock workflow for every run
- Explain-this-number drilldown on every cell
- Auditor packet exports and read-only auditor access
- Draft journal-entry output
What Apportix is not
- Not a GL replacement
- Not a full ERP
- Not direct accounting-system posting
- Not direct HUD or REAC submission
- Not an auditor or an audit opinion
- Not AI choosing allocation methods for you
Who it helps
Built for the people who answer the hard questions.
Different roles, same problem. When the question is how did we get that number, the answer needs to be in one place, not in someone’s head.
Defensible numbers at the board table.
Show the board where each allocation came from, with documented methods and a clean trail you can walk through line by line.
- Board-ready summaries that match the audit support
- One source of truth for FY methods and changes
- Less exposure when key staff leave
A repeatable close, documented every time.
Methods, rules, and approvals are versioned. Cycle runs stop depending on one workbook and one person’s memory.
- Versioned rules and basis tables, reused every cycle
- Approve and lock workflow with full audit log
- Clear handoffs between staff, fee accountants, consultants, and auditors
Support packets that already answer the questions.
Read-only auditor access, traceable allocations, and exports built around the questions your auditor actually asks.
- Source, rule, run, and approval on every figure
- Auditor packet exports as a single artifact
- Explainable numbers without back-and-forth email chains
Pricing
Pricing follows the cycle.
Most engagements start with a fixed-scope initial allocation cycle. Year one carries the setup and the first run. Recurring years are lower because the model is already live.
Recurring support is scoped around cadence. Annual, semiannual, quarterly, or ongoing.
Year one
Setup, model build, and the first operated cycle.
Recurring
Lower, because the model is already configured and preserved.
How we scope
By model complexity, number of cycles, outputs, and support level. Not per row or per spreadsheet tab.
Security and procurement
Built for the questions procurement asks.
Finance, IT, and procurement teams ask about access, data handling, exports, and system boundaries early. Here is the short version.
Managed cloud application infrastructure
Agency-level data separation and tenant-scoped access controls
Role-based permissions for preparers, approvers, administrators, viewers, and auditor access
Private storage for uploaded source files and generated support packages
Audit logs for key setup, run, approval, lock, export, and administrative events
Controlled exports for allocation schedules, support packets, and draft journal-entry output
Tokenized, limited-scope auditor access when enabled
No direct GL posting, no direct HUD/REAC submission, and no replacement of the accounting system
Only the data needed to complete the scoped allocation cycle
W-9, insurance, security overview, and vendor documents available on request
A security and procurement overview is available for active evaluations.
Note from the founder
Apportix is being built from inside the workflow, not from a generic SaaS checklist.
That means the product takes the parts of PHA finance that everyone has been quietly carrying in spreadsheets, the methods, the version history, the review steps, the lock, the auditor handoff, and treats them as first-class. The goal is not a dashboard. The goal is a finance workflow your team can actually defend.
Implementation is founder-led, with PHA finance and CPA support available for methodology review.
