Fixed assets
Fixed assets are the durable goods acquired for the company’s activity. Simon detects them from your invoices or your FEC, computes the depreciation schedule (straight-line or declining-balance) and posts the depreciation charges month after month. Ordinary expenses, on the other hand, stay in the usual invoice flow.
On a fixed asset, you validate the nature of the good, its account, the acquisition date, the amount excluding tax, the duration, the depreciation method, and — in case of an import — the depreciation already applied.
What is a fixed asset?
A good acquired for durable use (more than a year) and whose amount excluding tax exceeds the configured capitalization threshold is recorded as a fixed asset, in the classes:
| Class | Nature | Examples |
|---|---|---|
| 20 | Intangible | Software, patents, goodwill |
| 21 | Tangible | Computer equipment, furniture, vehicles |
| 23 | In progress | Fixed assets under production |
Automatic detection
Simon detects fixed assets from two sources.
From supplier invoices
When qualifying a supplier invoice whose amount excluding tax reaches the capitalization threshold, Simon analyzes:
- The proposed accounting account (classes 20, 21, 23)
- The designation of the good on the invoice
- The acquisition date (invoice date)
If the criteria are met, Simon automatically generates the corresponding fixed asset.
From a FEC import
When importing a FEC, Simon scans all the entries of the class 2 accounts and deduces the existing fixed assets. It groups the entries by account, computes the gross value (debit balance) and retrieves the accumulated depreciation in the corresponding 28 accounts.
Derived accounts (PCG convention)
From the fixed asset account, Simon automatically derives the depreciation and charge accounts:
| Asset account | Depreciation account | Charge account | Type |
|---|---|---|---|
2183 | 28183 | 68112 | Tangible |
2154 | 28154 | 68112 | Tangible |
205 | 2805 | 68111 | Intangible |
The rule: for tangible fixed assets (class 21), the depreciation account is 28 + the account suffix. For intangible ones (class 20), it is 280 + the suffix.
Creating a fixed asset
Automatic (at posting)
When a document is posted and its qualification indicates a fixed asset, Simon:
- Creates the fixed asset (being depreciated)
- Generates the complete depreciation schedule
- Links the fixed asset to the source document
Manual (via the agent or the UI)
The agent (or the user via the interface) can create a fixed asset directly. The required fields are:
| Field | Description |
|---|---|
| Designation | Name of the good (e.g. “MacBook Pro M4”) |
| Acquisition date | Date of the invoice or of commissioning |
| Amount excl. tax | Acquisition price excluding tax |
| Duration | Depreciation duration in months (e.g. 36) |
| Account | PCG account (e.g. 2183 for computer equipment) |
The optional fields include the residual value, the depreciation method (straight-line by default) and the link to the source document.
Depreciation schedule
Straight-line method
Straight-line depreciation spreads the depreciable amount uniformly over the useful life:
monthly_charge = (base - residual_value) / duration_in_monthsThe pro rata temporis is applied to the first month if commissioning does not fall on the 1st of the month. The last month absorbs the rounding difference so that the total depreciated is always exact.
Declining-balance method
Declining-balance depreciation applies a fiscal coefficient to the straight-line rate — a coefficient that increases with the depreciation duration. Each year, Simon compares the declining-balance rate to the straight-line rate over the remaining duration; as soon as straight-line becomes more advantageous, it automatically switches to straight-line for the remaining periods.
Parameter validation
Before any calculation, Simon checks:
- Strictly positive amount
- Duration between 12 and 240 months
- Straight-line or declining-balance method
- Residual value less than or equal to 20% of the base
- Start date not in the future
Posting the depreciation charges
The depreciation entries are generated for all instalments not yet posted up to a given date.
For each line of the schedule:
| Direction | Account | Label |
|---|---|---|
| Debit | 68112 (or 68111) | Depreciation charge [designation] |
| Credit | 28xxx | Accumulated depreciation [designation] |
The entries are posted in the IM journal (Fixed assets). Each line of the schedule is marked as posted to avoid duplicates.
Disposal of a fixed asset
When a good is sold or scrapped, the fixed asset is disposed: you simply mark it as such, with the disposal date and amount.
The disposal entries are generated automatically:
- Removal from assets: credit of the fixed asset account (e.g. 2183)
- Reversal of depreciation: debit of the accumulated depreciation account (e.g. 28183)
- NBV (net book value): exceptional expense if NBV > 0
- Disposal price: exceptional income
Modification and recalculation
When the depreciation method or duration is modified, Simon automatically recalculates the schedule for the periods not yet posted. The entries already posted are kept — the recalculation only covers the amount remaining to be depreciated.
