Optimising company expenses before the end of the accounting year in Bulgaria means reviewing, analysing, and automating your processes. Digital solutions like ood.bg help you manage costs more efficiently and meet legal requirements.

## What types of expenses can be optimised before the year-end in Bulgaria?
The most commonly optimised expenses are materials, external services, administrative, transport, and inventory costs. Review all expense documents – invoices, protocols, and warehouse transactions – to determine which costs can be reduced or postponed.

**Example:**
| Category         | 2023 Expense (BGN) | Possible Reduction (%) | New Expense (BGN) |
|------------------|-------------------|-----------------------|-------------------|
| Materials        | 30,000            | 10%                   | 27,000            |
| External services| 20,000            | 15%                   | 17,000            |
| Transport        | 8,000             | 5%                    | 7,600             |

Total potential savings for the year: 3,400 BGN by reviewing and optimising main expense categories.

## What are the steps for effective expense control and reduction?
Effective control requires a systematic review of all expenses by category, trend analysis, and applying measures to reduce or optimise costs. Digital tools enable automated data collection and analysis.

**Steps:**
1. Gather all expense documents for the year (invoices, protocols, warehouse operations).
2. Classify expenses by category and supplier.
3. Use [ood.bg's turnover and VAT reports](https://ood.bg/en/features#vat) to analyse the largest expense items.
4. Review supplier contracts and look for opportunities to negotiate better terms.
5. Implement automation for recurring expenses via ood.bg (e.g. automatic document issuance and delivery).

**Example:** If your company has a monthly external services expense of 2,000 BGN, negotiation and optimisation could reduce this by 10% (200 BGN per month, or 2,400 BGN annually).

## What documents and reports are required for expense optimisation?
You need all primary expense documents (invoices, protocols, warehouse transactions), as well as monthly VAT and turnover reports. Documents must be sequentially numbered and comply with the Bulgarian VAT Act (source: nra.bg).

**Required documents and reports:**
- Invoices and protocols with a 10-digit number, no gaps
- Warehouse operations (write-offs, inventory)
- Monthly VAT return (справка-декларация) by the 14th of the following month
- Turnover reports by item, supplier, and warehouse

**Example:**
| Document           | Requirement                         |
|--------------------|-------------------------------------|
| Invoice            | 10-digit number, no gaps            |
| Protocol           | Sequential numbering                |
| Warehouse write-off| Detailed description                |
