Neptune Data / Bespoke Applications
Every firm has one workflow that defines it — and generic tools that almost fit it. Neptune builds the application that actually does. Think of it as consulting whose deliverable is software: scoped with your practitioners like an engagement, validated against your own reference work product like a review, and delivered on a platform built for confidential work — where it keeps running long after the engagement ends.
The model
It runs like an engagement: four phases, each with your practitioners in the loop. But where an engagement would end in findings, this one ends in an application whose rules encode how your firm does the work — and that's when it starts earning.
We sit with the people who do the work. What comes in, what goes out, what "correct" means, and which judgment calls belong to humans.
Extraction rules, reconciliation checks and outputs modeled on your real documents — statements, schedules, side letters, the messy ones.
Output is scored against work product your firm has already signed off on, document by document, until the differences are explainable.
The app ships into your workspace with lineage, review tooling, cost visibility and your corrections feeding back into future runs.
Spotlight case study
Built with a tax practice whose clients hold many fund interests: every spring, a mountain of Schedule K-1 packages that must become one reconciled workbook. This is what a bespoke application looks like at full depth.
A single K-1 "package" is 40–60 pages, and most of it is noise. The suite knows the anatomy — what to read, what to cross-reference, and what to ignore entirely.
The extraction is governed by hard rules a reviewer can hold it to — encoded from how the firm's own preparers check the work.
Every box's components must sum exactly to its printed total — the K-1 face
amount, or the statement's own TOTAL line. A component can never
stand in for a whole box, and no component gets dropped.
Foreign amounts are the sum of the foreign category columns — never the U.S. source column, never the grand total. The most common human error in foreign tax credit prep, eliminated by construction.
Beginning capital + contributions + income + withdrawals must reach ending capital. Anything unexplained surfaces as an explicit adjustment line — never silently absorbed.
Where the package includes an Item L income reconciliation, extracted line items must reproduce it before the run is accepted — even $1 items count.
One Excel workbook per tax year: a detail tab with one column per fund and canonical rows for every box; a foreign tax credit tab; a capital-changes partner allocation worksheet; a non-passive split. Totals are live formulas — corrections never go stale. Prior-year columns and differences appear automatically when last season's data exists.
The same tabs in the browser. Every cell knows its lineage: extracted figures show the statement lines behind them and open the source PDF to the recorded page with the amount highlighted; calculated figures show their arithmetic as a process chart with every component one click away. Cycle through every place a figure appears in the package.
A visual of strategies, funds and capital flows — phantom income and loss positions flagged — plus a conversational analyst that answers against the extracted data. Corrections agreed in review are remembered and applied to future extraction runs automatically.
The suite was built against real portfolios and scored against the firm's own hand-built reference workbooks — box by box, fund by fund — with every disagreement adjudicated against the source PDF until the remaining differences were explainable and documented. That validation loop never ends: reviewer corrections keep feeding the system.
Also built on the bespoke engine
Credit agreements and loan files into structured abstracts: parties, economics, covenants, defaults and maturities — with the source language quoted.
Commercial leases into consistent abstracts: term, rent schedules, options, CAM, assignment and termination rights — portfolio-comparable.
Organizational documents into an entity map with ownership, control and succession paths — the picture estate counsel draws by hand, generated.
Each of these started the same way the K-1 Suite did: a firm, a workflow, a stack of documents and a reference standard. Yours would too.
